IPA: /ˈtaɪd.ləs/
KK: /ˈtaɪd.ləs/
Describing an area or body of water that does not experience tides or changes in water level due to tidal forces.
The tideless sea was calm and still, with no waves crashing against the shore.
Tideless → It is formed from "tide" (from Old English *tīd*, meaning time or season) and "-less" (meaning without). The word "tideless" means without tide or lacking the regular ebb and flow of the tide.
Think of 'tide' as a measure of time or season, and remember that 'tideless' means lacking that regular flow.
