Dear student,

No of words starting from A=4!= 24
No of words starting from E=4!= 24
No of words starting from H=4!= 24
No of words starting from MA=3!= 6
No of words starting from ME=3!= 6
Total of above = 24+24+24+6+6=84
85th word will start with MH and as per dictionary it will be MHAES
and 86th will be MHASE
So, last letted of 86th word will be 'E'
