My “everything should be completely orderly” comp-sci brain is always triggered by these almost trivial problems that end up being much more interesting.

Is the suffix pattern based on the pronunciation of the syllable(s) before the suffix? If one wanted to improve upon your work for unknown names, rather than consider the letters used, would you have to do some NLP on the name to get a representation of the pronunciation and look that up (in a trie or otherwise)?

Careful, this is how you fall down the Are Dependent Types The Answer?? hole.

Not sure what that's supposed to mean, but if Icelandic is anything like my native language in this, then it is indeed a pronunciation based thing. Which should make sense, since languages are (historically) spoken first, written second.

Hmm, good idea. There are names that have the exact same pronunciation yet have different patterns of declension, for example:

- Ástvaldur -> ur,,i,ar - Baldur -> ur,ur,ri,urs

The "aldur" ending is pronounced in the exact same manner, but applying the declension pattern of "Ástvaldur" to "Baldur" would yield:

- Baldur - Bald - Baldi - Baldar

The three last forms feel very wrong (I asked my partner to verify and she cringed).

Spoken Icelandic is surprisingly close to its written form. I wouldn't expect very different results for the trie if a "phonetic" version of names and their endings were used instead of their written forms
