indicating a person skilled or involved in a branch of study denoted by a noun ending in -logy (such as biologist corresponding to biology)
表示“…学家”, “…专家”。
-logistan ending resulting from the addition of -ist to ns. in -logy, forming ns. with the general sense ‘one who is versed in ―logy’. It is now the only living formative with this function, the older equivalents -loger, -logian, -logue occurring only in very few words (most of which are obsolescent). The formation is mainly English, though a few examples, as étymologiste, chronologiste, have existed in Fr. from the 16th or 17th c., and others, as zoologiste, appear first in the 19th c.
-logist/lədʒɪst/suffix.

Forming nouns with the sense ‘an expert in or student of the specified branch of knowledge, a person skilled in —logy', as etymologist, geologist, heresiologist, ideologist, zoologist, etc.

A person who studies or is an expert in the related -logy.

Usage notes
Relatively few terms are directly derived using this suffix. Terms ending in logist are often derived from words formed in other languages or by suffixing -ist to a word ending in logy, as dermatologist = dermatology + -ist and genealogist = genealogy + -ist.
