In French, there is a verb "retrouver" (literally "re-find", or "find again") which means "find something that you lost and were searching for" (there the meaning "re-"/"again" is expressed by the morph "re-").
How do we express this term in Japanese?
Do we still use the verb 見つける mitsukeru 'to find'?
An example sentence would be "Mary is happy, she finally found the key (she was looking for since she lost it)".
In French, the part in parenthesis could be ommitted if the word "retrouver" ('re-find') is used instead of "trouver ('find'), since the meaning expressed in the part in parenthesis is expressed by the morph "re-".
