Extremely rickety houses having a light tone (5)
I believe the answer is:
lyric
'a light tone' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'extremely rickety houses having' is the wordplay.
'having' indicates the answer is hidden within the clue.
'LYRIC' is hidden in the letters of 'extremely rickety houses'.
Can you help me to learn more?
(Other definitions for lyric that I've seen before include "Song's text" , "Poetic lines" , "Short poem of songlike quality" , "something to sing about? On the contrary" , "Of poetry that expresses the poet's feelings" .)
