Greetings.
I am trying to really learn the -mi verbs once and for all. It seems to me that the best way to do this is learn them all at once, noticing the patterns and delving a little into the philology. What I’ve written here is what I currently know about the verbs in general (what I call ‘the three classes’) and then my version of the present indicative active of class I (as far as I’ve got so far). I’m hoping that people will find my horrible mistakes, add their own knowledge/thoughts on the patterns or philology, or even find it useful.
The three classes:
I) Reduplicated stem + mi (didomi, tithemi, istemi, hiemi)
II) Stem + mi (eimi, eimi, phemi)
III) Stem + numi (deiknumi etc.)
I) Reduplicated Stem + mi
These are thematic - the vowel of the stem alternates between long and short forms. The vowel of the stem can either be e (alternating between epsilon and iota) or o (alternating between omicron and omega).
Some tenses use the reduplicated stem - tith, did, ist, hi; others use the plain stem - th, d, st, he [stems can be explained by Grassman’s Law and loss of *y]
Verb form: stem + thematic vowel + ending.
Present Indicative:
Reduplicated stem + long vowel for singular/short vowel for plural + mi, s, si(n), men, te, asi e.g. didwmi, didws, didwsi; didomen, didote, didoasi
