Crossword Genius

To put together tense with shy is silly (10)

Ross

I believe the answer is:

synthesise

'to put together' is the definition.
('put together'->'synthesize' is in my internal thesaurus and 'ize'->'ise')

'tense with shy is silly' is the wordplay.
'with' is a charade indicator (letters next to each other).
'silly' is an anagram indicator.
'tense'+'shy'+'is'='tenseshyis'
'tenseshyis' with letters rearranged gives 'SYNTHESISE'.

I've seen this clue in The Telegraph.
