Strengthening device sufficient provided current included? Right (9)
I believe the answer is:
amplifier
'strengthening device' is the definition.
'amplifier' can be an answer for 'device' (thesaurus). I'm unsure of the 'strengthening' bit.
'sufficient provided current included? right' is the wordplay.
'sufficient' becomes 'ample' (both can mean enough).
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'current' becomes 'I' (symbol for electric current).
'included?' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'if'+'i'='ifi'
'ample' going around 'ifi' is 'amplifie'.
'amplifie'+'r'='AMPLIFIER'
Can you help me to learn more?
(Other definitions for amplifier that I've seen before include "Device augmenting sound" , "Loudspeaker driver" , "Electronic equipment to increase signal strength" , "Device that strengthens" , "Device to boost sound levels" .)
