Height from position seeing lake for first time (8)
I believe the answer is:
altitude
'height' is the definition.
(synonyms)
'from position seeing lake for first time' is the wordplay.
I cannot really understand how this works, but
'from' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'lake' could be 'l' (geographical abbreviation) and 'l' is present in the answer.
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is located in the answer.
'time' could be 't' (abbreviation) and 't' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for altitude that I've seen before include "Height (above ground)" , "Lofty position" , "Elevation above sea level" , "Angular distance above the horizon" , "Height above sea level" .)
