Helped temporarily, with “over”

TIDED …

Think of what you might do to keep someone afloat until more permanent support arrives, like a lifeline in a tough spot.

The clue plays on the phrase "tide over," which means to help someone through a difficult period temporarily. "With 'over'" signals that you take the word "tided" and pair it with "over" to form the full expression. The answer is just the first part, "TIDED," since the clue hints at the start of the phrase. It’s a common crossword trick where the clue implies a longer phrase but only wants a piece of it.
