estimable

The word "estimable" originates from the Latin verb aestimare, meaning to value, appraise, or judge the worth of something. The suffix -abilis was added to form the Late Latin term aestimabilis, signifying "that can be valued or appraised." This literal sense of being capable of estimation evolved in French (estimable) and later English to carry the more abstract meaning of being worthy of esteem or respect. Thus, the logic of the word traces a path from a concrete act of valuation to the abstract quality of being valuable or admirable in character.
