approximant /w/

/w/ is a voiced labial velar approximant. It's the sound that most Brits who speak General British produce at the beginning of this sentence: "Woe gates here zoo den Laser roymen." (sorry for the weak joke)
Seen aerodynamically /w/ displays laminar airflow, so - in auditory terms - there's no audible friction. If I'm not mistaken, the term 'approximant' was first proposed by the late Peter Ladefoged in 1964 in his monograph A Phonetic Study of West African Languages, in which he writes on p. 24 (I quote from the second ed. of 1968):
"The term approximant is used here to describe a sound which belongs to the phonetic class vocoid or central resonant oral [...], and simultaneously to the phonological class consonant in that it occurs in the same phontactic patterns as stops, fricatives and nasals."

[w] is an approximant; others would call it a frictionless continuant. We need both lip-rounding (at least in careful speech) and a frictionless narrowing of tongue and velum to articulate the sound. That's why the sound is classified as labial velar. It's called 'voiced' because the vocal folds vibrate.

  1. ... which can all be summed up by saying that it is the nonsyllabic congener of /u/, or, equivalently, the semivowel corresponding to /u/.
