つとめて

Etymology 1
Compound of 🇰🇲.

A surface analysis suggests that the -mete may have originated as the conjunctive -te form of the verb-forming suffix -meru (“to make something become more [of the suffixed term]”), as in words like. That said, -meru usually produces transitive verbs, contrasting with intransitive suffix -maru, and a transitive sense in this word seems out of place. Then again, at least one monolingual Japanese resource derives verb from the same root  and this suffix -meru.

First cited to  of the early 900s.
