abstain
To choose on purpose not to do something.
To abstain means to choose not to do something, especially something you could do but deliberately avoid. When someone abstains from voting, they're present for the vote but choose not to say yes or no. When a student abstains from eating candy during Lent, they're choosing to go without it for a specific period.
The word carries a sense of self-control and purposeful choice. You make an active decision to hold back. A vegetarian abstains from eating meat. Someone might abstain from watching TV during exam week to focus on studying.
In formal votes, abstention is important because it's different from being absent or voting no. When a school council member abstains, they're saying “I'm not taking a side on this issue,” which might happen if they have a conflict of interest or need more information.
The word suggests restraint and discipline. Athletes might abstain from junk food while training. Someone abstaining from gossip is choosing not to participate, even when others around them are talking. That choice to hold back, to not join in when you easily could, is what makes something true abstention.
