A
strong verb, especially in
Germanic languages, is one which experiences a
vowel change in the stem when forming the past tenses.
Examples:
English:
sit -> sat
break -> broken
Swedish:
skriva -> skrev (To write)
dricka -> drack (To drink)
Latin's closest approximation to strong verbs are third-
conjugation verbs, whose perfect stems may be radically different from their present stems.
