Nicola - Although not really the same verbs which you are asking about, http://dlmcn.com/ir_verbs.html contains the results of research I did on vowel changes in certain "-ir" verbs. For example, for me it is helpful
to remember that advertir, convertir, invertir, divertir
and the others which end in "-vertir", all adopt the e>ie stem-change in [much of] the present tense, as too do all the "-erir" ones [sugerir, diferir, interferir, referir, transferir, preferir, inferir etc.] However, those which terminate in "-ergir" [sumergir, divergir, and convergir] do *not* undergo any vowel change. In the third category, all "-etir" verbs [e.g. repetir, competir, derretir] - as well as "-egir" ones - replace the 'e' by 'i' in the present tense [apart from the nosotros and vosotros forms, of course].
How to remember
Hi, is there some kind of rule with the verbs that stem change to ue or is it just a case of learning and remembering which ones do?
Thanks :)
Hola Nicola
It'd be useful if there was some kind of rule to know which verbs undergo that change but no, unfortunately it is a memorising exercise...
Saludos

Notice contar isn’t in this list?
Hi there, I notice contar wasn’t in this list? Or is it always the case that an -ar- verb ending in “ontar” will change its stem?
Hola Francis,
I just added the verb "contar" to this list as a o > ue verb in the present. Bear in mind though that not all verbs with an -o in their stem undergo this vowel change. For example, verbs like "montar" = to ride or "borrar" = to delete are completely regular verbs.
Saludos,
Inma

Do we have a list of ir er verbs with the consonant o in the stem which do not change?
Hola Dennis
I'm afraid not. We tend to make lists of verbs that undergo some sort of irregularity.
To name some of those verbs that have an -o in the stem and don't change to -ue, you have for example:
Cortar - to cut
Notar - to realise
Frotar - to scrub
Votar - to vote
Engordar - to get fat
Coser - to sew
Comer - to eat
Coger - to take
Poner - to put
