Crossword Genius

Splendid wave (5)

Ross

I believe the answer is:

swell

This clue is a double definition.

'splendid' is the first definition.
(I've seen this before)

'wave' is the second definition.
(swell is a kind of wave)

(Other definitions for swell that I've seen before include "Enlarge; excellent" , "Rise into waves" , "Expand abnormally" , "'Increase in size, number etc (5)'" , "Burgeon" .)

I've seen this clue in The Times.
