The form of the past participle for strong verbs is not that of the simple past tense.
“have run”, not “have ran”
“have rung”, not “have rang”
“have drunk”, not “have drank”
“have sung”, not have “have sang”
&c
Translators for whom something other than English is a first language should make a chart of all the strong verbs and tape it up near their work areas.
