Noah’s craft finally disappeared in a desert for its resting place (6)
I believe the answer is:
ararat
'place' is the definition.
(I know that Ararat is or was a crest)
'noah's craft finally disappeared in a desert for its resting' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'desert' could be 'rat' (abandon treacherously) and 'rat' is found in the answer.
The remaining letters 'ra' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ararat that I've seen before include "Mountain where the Ark grounded" , "Ark's supposed resting place" , "original dry dock" , "Mount where Noah's Ark came to rest" , "Turkish Mount on which Noah's Ark is said to lie" .)
