Interlinear Glossing: Methods, Conventions, and Best Practices

FLEx (Fieldworks Language Explorer) is a free software tool developed by SIL International for linguistic fieldwork, featuring three main panels: a navigation panel with tools for managing different data areas, a central panel displaying lists of entries, and a details panel showing information about selected entries. The software includes four primary modules: Lexicon for managing vocabulary entries with fields for pronunciation, definitions, audio recordings, and grammatical information; Texts and Words for interlinearized texts, concordances, and morphological analysis; Grammar for defining grammatical classes and their properties; and an Anthropological Notebook for recording cultural observations. The program supports exporting data to various formats including printed dictionaries and digital formats, making it suitable for language documentation, analysis, and publication.

This comprehensive tutorial covers the complete workflow for linguistic fieldwork using ELAN and FLEx. ELAN (from Max Planck Institute) annotates audio/video by linking waves to segments, while FLEx (from SIL) manages linguistic data for glossing and dictionary building. The workflow involves: (1) Preparing by installing programs, ensuring WAV format audio, and obtaining Ethnologue language codes; (2) Setting up ELAN with linguistic types (words, morph, gloss, text, phrase, blank) and tiers (interlinear title, transcription, translation, participant) using language codes; (3) Creating templates for reuse; (4) Transcribing audio using segmentation mode and transcription mode; (5) Exporting to FLEx format; (6) Creating FLEx projects with language codes; (7) Importing and numbering text; (8) Creating lexical entries and morpheme boundaries; (9) Configuring interlinear display; (10) Exporting glossed text; (11) Reimporting to ELAN and reorganizing tiers for final presentation. This integrated approach enables comprehensive linguistic analysis with audio-text alignment throughout the process.

This tutorial demonstrates how to create lexical entries in FieldWorks Language Explorer (FLEx) by navigating to the Lexicon section, inserting entries through the Insert menu or keyboard shortcuts, and filling in fields for the word form, gloss (translation), and grammatical category; the video also explains how to add morphological elements like prefixes and suffixes, and emphasizes the importance of having multiple analysis systems (such as English and Spanish) to access all available grammatical categories in the software.

This video demonstrates how to create a new project in SIL's Fieldworks Language Explorer (FLEx) software, showing the process of entering a project name, selecting a vernacular language (the local language being studied), choosing an analysis language (such as English), and configuring optional settings like the OCM enhanced outline for cultural materials, all while providing guidance on navigating the project creation wizard.

Interlinear glossing provides deeper insight into how languages convey information compared to simple translation by revealing the structural components that build meaning. Morphemes are the smallest units of linguistic information, functioning like atoms in words—for example, 'unbelievable' contains 'un' (negation), 'believe' (verb), and 'able' (suffix). Five core symbols exist: hyphens (-) for segmentable morphemes, underscores (_) for unsegmentable elements requiring multiple metalanguage words, periods (.) for morphemes containing multiple simultaneous features, angle brackets (⟨⟩) for infixes and poly-personal relationships, and double hyphens (--) for circumfixes. Abbreviations streamline glossing but vary by author—common choices include 'pre' for present tense and 'F' for feminine. Formatting options include reducing font size for morphemes in word processors, or using LaTeX packages like expex with commands \gla, \glb, and \glft. However, glosses have limitations: they cannot replace thorough explanations of grammatical categories, omit word order information essential for understanding, and only capture semantic information—pragmatic elements like context-dependent meanings, slang, idioms, and conversational implications remain challenging to represent.

This tutorial demonstrates how to use the free Adobe InDesign script 'align-glosses.jsx' to automatically align linguistic interlinear glosses, which consist of three lines: the original language text, word-by-word grammatical breakdowns, and English translations. The script eliminates the tedious, slow, and error-prone process of manually aligning these components, making it particularly valuable for linguists and language researchers who need to format complex multilingual examples efficiently.

Example environments in TeX are created using begin and end commands with content indented by a single space. Multiple examples can be nested for hierarchical structures. The gb4e package provides example environments for linguistic analysis, including commands to prevent automatic math mode entry. Glossaries are created using the glossaries package with begin glossary, glossentry commands, and end glossary. Each entry includes a label, title, and text. Entries are separated by blank lines. This structure is essential for linguistic papers requiring systematic presentation of examples and terminology.

To display LaTeX code or programming code literally (without compilation), use the verbatim environment. Syntax: 'verbatim' followed by the text in braces. For text alignment: use 'center' environment for centered text, 'left' for left-aligned (default), and 'right' for right-aligned. For formatting: use 'textbf' for bold text, 'textit' for italic text, and 'underline' for underlined text. Alternative syntax for bold text uses '\bf' inside braces. Multiple formatting commands can be combined, such as 'textbf{textit{text}}' for bold italic text. For font sizes: 'tiny' (smallest), 'scriptsize', 'footnotesize', 'small', 'normalsize' (default, 12pt), 'large', 'Large', 'LARGE', 'huge', 'Huge' (largest). For horizontal space, use 'hspace' followed by a length value (e.g., 'hspace{2cm}'). For vertical space, use 'vspace' followed by a length value (e.g., 'vspace{2cm}'). Negative values in 'hspace' move text to the left.

The Index dialog box allows customization of the glossary format. You can choose the format (Classic, Classic with page numbers, etc.), specify the number of columns (1, 2, or more), and align page numbers to the left or right. The instructor demonstrates selecting 'Classic' format with a single column and aligning page numbers to the right. The preview in the dialog box shows how the glossary will appear, with terms listed alphabetically and page numbers on the right side.

Field linguists document undocumented languages worldwide by collecting extensive linguistic data. The ideal method involves living among a community for extended periods (often decades) to learn the language authentically. When this isn't possible, researchers use alternative methods: finding bilingual translators, recording conversations with portable devices, and transcribing hours of audio recordings. This work is essential because many languages remain undocumented, and without systematic recording, they risk disappearing without scientific study. Field linguists contribute to preserving linguistic diversity and building comprehensive grammars and dictionaries for underrepresented languages.

Interlinear glossing is a standardized method for documenting language morphology that uses three aligned lines: the first line shows the original text (in orthography or IPA), the second line breaks down each morpheme with dashes separating different morphemes and dots separating different meanings within a single morpheme, and the third line provides the full translation; this technique works differently across language types—being simple for isolating languages like Vietnamese where each word has one morpheme, requiring morpheme separation for agglutinative languages like Turkish, and needing additional meaning separation for fusional languages like Spanish where one morpheme can pack multiple grammatical features.

Interlinear glossing is a standardized methodology for morphological analysis where each word breaks down into component morphemes with translations. Each morpheme receives a gloss using standardized abbreviations (LISG rules) indicating grammatical functions: PL for plural, 3SG for third person singular, ERG for ergative case, etc. Morphemes align vertically with glosses for readability, using dashes between separate morphemes and dots when morphemes cannot be cleanly separated (like English 'mice' or 'bark'). This technique allows linguists to understand how languages encode various types of meaning systematically.

Interlinear glossing (also called LIFG glossing) is a standardized protocol for documenting linguistic data. Linguists break down sentences into individual morphemes and assign translations/glosses to each. For example, 'dogs' becomes 'dog.PL' and 'barked' becomes 'bark.PST.' This systematic approach allows researchers to isolate and understand the function of each morpheme in conveying meaning.

Glossing is a method for transcribing the morphology and syntax of languages. An interlinear gloss typically has three lines: (1) the original text (transcribed in phonetic notation), (2) the morpheme-by-morpheme description, and (3) the translation. Each morpheme is aligned with its meaning below it. Conventions include using hyphens for separable morphemes and periods for grammatical content that cannot be easily separated. This method allows linguists to document and analyze language structure systematically.
