What is a word that means "to make profound"?

For example,

This onion will [infinitive] the stock.

These colors [3rd person plural] the painting.

Deepen doesn't quite cut it, and I can't use the imaginary words "profund-ize" or "profund-iate" in a formal setting.

Any suggestions?

    Would a slightly different construction like "give gravity to" cut it?

  • @TimLymington: a stock that has a deep, rich taste, I would guess. Jul 16, 2013 at 10:39

I would suggest either deepen or enrich. Deepen does carry a slight implication that whatever is being deepened is already a bit deep (e.g. a well or a pit); but you can enrich something which isn't already rich or deep.


Enhance to improve the quality, amount, or strength of something Longman dictionary: to improve something Free Dictionary: to intensify or increase in quality, value, power, etc.; improve; augment

  • These onions will enhance (the flavour of) this stock soup.

  • These colours enhance (the play of light and shadow in) the painting.
