back-in comb. is used in many relations, substantive, adjective, and adverbial (rarely verbal), often difficult to separate, and in various senses. In some of these the combination is very loose, the use of the hyphen being almost optional.This is especially the case, when back is capable of being viewed as an adj., in which aspect the hyphen would not be used, e.g. back-yard or back yard, back-stroke or back stroke. As a rule, the use of the hyphen implies that the combination (in the case in point) has not the general and purely descriptive value of the two words, but is in some respect specialized or appropriated as a specific name.A.

词汇	back-
词根词缀	OED SOED Wiktionary back-in comb. is used in many relations, substantive, adjective, and adverbial (rarely verbal), often difficult to separate, and in various senses. In some of these the combination is very loose, the use of the hyphen being almost optional.This is especially the case, when back is capable of being viewed as an adj., in which aspect the hyphen would not be used, e.g. back-yard or back yard, back-stroke or back stroke. As a rule, the use of the hyphen implies that the combination (in the case in point) has not the general and purely descriptive value of the two words, but is in some respect specialized or appropriated as a specific name.A.
