Sense: verb/1
These words all involve becoming part of a group or activity, but they differ in formality and scope. 'Enroll' and 'register' are both fairly formal and imply an official list or record — you enroll in a degree program or register for a conference. 'Sign up' is informal and suggests a quick, low-commitment decision: 'I signed up for a free webinar.' 'Join' is the broadest and most neutral — you can join a club, a team, or a conversation. 'Enlist' is more specific, traditionally used for military service, though it can extend metaphorically to 'enlist support' or 'enlist help.' Use 'enroll' when official paperwork or a membership list is involved, and 'sign up' for casual or one-time activities.

Etymology
The word 'enroll' comes from the Old French 'enroller' (13th century), which literally meant 'to record on a roll of parchment.' A 'roll' was a scroll listing names, so 'enrolling' someone originally meant writing their name onto such a list. The spelling with a double 'l' is standard in American English, while British English uses 'enrol' (one 'l').
