a tad
Just ever so
A tad is a small amount—slightly more than nothing: The soup needs a tad more salt.
It works as an adverb meaning slightly or somewhat: He seemed a tad nervous, It's a tad expensive.
The word is informal and understated, often used to soften criticism or make a request seem modest.
