IPA: /ˈtʌɡləs/
KK: /tʌɡləs/
Not having a pull or a tug; lacking the action of pulling something.
The tugless design of the boat made it easier to maneuver in tight spaces.
The word 'tugless' is formed from 'tug' (of uncertain origin, possibly related to the Middle English 'tuggen', meaning to pull or drag) and '-less' (meaning without). Therefore, 'tugless' describes something that is without the need to pull or drag.
Think of 'tug' meaning to pull and '-less' meaning without — so 'tugless' means without the need to pull.
