Answer:
SMART
Explanation:
In the context, the 'first', 'second', third', 'fourth' and the 'last' refers to an individual letter in that word.
My 'first' in the word 'sugar' is -- S
My 'second' in the word 'swim' is -- M
My 'third' in the word 'apple' is -- A
My 'fourth' in the word 'ring' is -- R
My 'last' in the word 'ten' is -- T
Thus, "SMART" is the word and it is definitely a complimentary word.
