Obsequiously flatter Lauda, injured before that race ends (7)
I believe the answer is:
adulate
'obsequiously flatter' is the definition.
'adulate' can be an answer for 'flatter' (adulating is a kind of flattering). I am not certain of the 'obsequiously' bit.
'lauda injured before that race ends' is the wordplay.
'injured' indicates anagramming the letters.
'before' says to put letters next to each other.
'ends' says to take the final letters.
The last letters of 'that race' are 'te'.
'lauda' is an anagram of 'adula'.
'adula'+'te'='ADULATE'
Can you help me to learn more?
(Other definitions for adulate that I've seen before include "Praise obsequiously" , "Worship" , "Flatter obsequiously" , "Praise excessively" , "Flatter excessively" .)
