Can -OH only be classified as a hydroxyl if it is by itself and not as part of a carboxylic acid? I've seen some sources where they classify an -OH part of a carboxylic acid as still a hydroxyl group, but other sources dont. and when does -OH become only a hydroxyl rather than an alcohol group? (i.e. use the 1-hydroxy. etc notation rather than ethan-1-ol notation.)

-OH should not be considered a hydroxyl group if it is also connected to a C=O
Similar thing with the ether link versus the ester link.

alcohol group doesnt exist, its called hydroxy.
and "-hydroxy" is used instead of "-ol"in functional group hierarchy. i.e. carboxyl group take predecence over hydroxy, hence in a molecule with both the hydroxy has to be suffix whilst the carboxyl is indicated in the suffix. [not on course]
and, there is no "carboxylic acid" functional group
