Tense, absorbed in endless waiting for fourth in line? (5)
I believe the answer is:
delta
'line?' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'tense absorbed in endless waiting for fourth' is the wordplay.
'tense' becomes 't' (grammatical abbreviation).
'absorbed in' indicates putting letters inside.
'endless' means to look at the middle letters.
'waiting' becomes 'abiding'.
'for fourth' becomes 'ela' (I can't justify this - if you can you should believe this answer much more).
The middle letter of 'abiding' is 'd'.
'd'+'ela'='dela'
't' going within 'dela' is 'DELTA'.
'in' is the link.
Can you help me to learn more?
(Other definitions for delta that I've seen before include "Fragmented estuary" , "Daedalus started with this" , "Fourth letter of the ancient Greek alphabet: river feature" , "Roughly triangular area of alluvial deposits" , "Area of alluvial deposit" .)
