The adjective feasible is something that can be done, made, or achieved.

Synonyms are reasonable, appropriate, attainable, or practical.

The word origins from Anglo-French (mid-15th century) faisible meaning “capable of being done, accomplished or carried out” and from Old French faisable meaning “possible, that may be done, easy, convenient” from fais-, stem of faire “do, make” (source also from Latin facere meaning “to make, do, perform”.
