Are there any Hebrew words that start with vav and mem?

Answer 1

Yes. The letter Vav is usually reserved as a prefix meaning "and". Native Hebrew words that begin with Vav are rare. Most words in Hebrew that begin with Vav are of foreign origin. Here is a short list of some native words:

ודאי (vah-DAH-ee) certainly

ודאות (vah-dah-OOT) certainty

וו (vav) hook

ורד (vered) rose

ותיק (vateek) veteran, a person with seniority

וידוי (vidui) confession

ותרני (vatrani) compliant

There are hundreds of words that begin with Mem (מ), thousands if you include verb conjugations and verbal nouns.
