Skip over, as a syllable (5)
I believe the answer is:
elide
'skip over as a syllable' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elide that I've seen before include "Omit (a sound or syllable) when speaking" , "Omit (syllables)" , "Omit vowel or syllable" , "Join together, merge" , "Omit (syllable) in speech" .)
