Identify the process illustrated.
rent. (from latin reddita, meaning things that are returned.) rente, the french original of rent, meant income. the english meaning is income from property.

a. amelioration
b. pejoration
c. generalization
d. specialization

Amelioration is a process in which the meaning of a word is upgraded - a word with a negative connotation develops a positive connotation. Pejoration is a process that goes the other way round (from a positive to a negative meaning). It is clear that these are not the options in this example.

It is now important to determine whether the trend goes from a general meaning to a more specified meaning, or the other way round. The trend is: something returned -> income -> income from rent, so the answer is specialization.
