Cherish

The word cherish carries deep feeling. Thankfully, unlike other similar words, the word does not seem to have become overused or drenched in sentimentality. Usually when people use the word, they mean it.
 
The word cherish has its origins in the Proto-Indo-European (PIE) root ka (to like, to desire) and Latin carus (dear, costly, beloved). Latin carus is the source of Italian, Spanish, and Portuguese caro.
 
In the early 14th century, the verb cherischen (to cherish, to hold as dear, to treat with tenderness and affection) comes to English from Old French cheriss and cheirir (to hold dear)
 
Latin carus and Italian caro are the source of Italian carezza (endearment) which comes to English in the 1640s as caress (a show of endearment, display of regard). In addition, Latin carus is the source of the word charity.
 
Cherish, caress, charity—all rooted in PIE ka.
