Good day? How terrible getting up in the morning (6)
I believe the answer is:
salaam
'good day?' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'terrible getting up in the morning' is the wordplay.
'terrible getting' becomes 'alas' (I can't justify this - if you can you should believe this answer much more).
'up' is a reversal indicator (in down clue: letters go upwards).
'in the morning' becomes 'am' (AM on a clock).
'alas' backwards is 'sala'.
'sala'+'am'='SALAAM'
'how' is the link.
Can you help me to learn more?
(Other definitions for salaam that I've seen before include "Gesture made by foreigner" , "Muslim form of salutation" , "Oriental salutation meaning peace" , "Oriental greeting with bow of obeisance" , "Muslim greeting gesture" .)
