Finding Language Codes

If you don't know a language's code:

# List all available and search
unimorph list --available | grep -i finnish
# Output: fin

# Or use the SIL database
# https://iso639-3.sil.org/code_tables/639/data

Setting Up Aliases

Create shortcuts for frequently used languages:

# ~/.config/unimorph/config.toml
[languages]
hebrew = "heb"
spanish = "spa"
german = "deu"
finnish = "fin"

Then use:

unimorph inflect -l hebrew כתב
# Resolves to: unimorph inflect -l heb כתב
