How did we get from “buy” to “bought”, from “Seek” to “Sought”, “Catch” to “Caught” and “Teach” to “Taught”? There’s more, of course (thought, fought, etc.). There must be some old english rule being applied here, anyone here that can explain it?
I know my 6-year old son would much rather say “buyed” and “teached”, if we could all agree to do away with these archaic past-tenses it’d make his life much easier.
Historical in English there was two types of verbs; a ‘weak’ and a ‘strong’. The weak used the ‘ed’ ending in past tense whereas strong used modification of the vowel. The tendency is for strong verbs to become weak. So irregular (strong) verbs gradually fade from use and are replaced by the regular (weak).
A good example of this is ‘dove’. It is currently vanishing and often replaced by ‘dived’, although the extent of this varies from region to region. Compare this to ‘drove’, also replaceable by ‘drived’, but not so commonly.
So the answer to the OP is to wait a few hundred years. But we can be sure that other equally irritating irregularities will have arisen in the same time.
