'mountain' is the definition.
(I've seen this before)

'family receiving letter from nato clash over nothing' is the wordplay.
'family' becomes 'kin' (synonyms).
'receiving' indicates putting letters inside.
'letter from nato' becomes 'lima' (NATO phonetic alphabet).
'clash' becomes 'jar' (synonyms).
'over nothing' becomes 'o' (O resembles 0. I am not sure about the 'over' bit.).
'kin' enclosing 'lima' is 'kiliman'.
'kiliman'+'jar'+'o'='KILIMANJARO'
