Question

This suffix always follows i.

Answer 1

Answer:

Suffixes are additional elements placed at the end of words, consisting of  letters or group of letters added at the end in order to change them, turning them into new words, sometimes turning a verb into an adjective and so on, and sometimes even modifying the root of that word; so in English grammar if the word to be change ends with "Y", an "i" is always added in order to use the suffix "-able",

e.g. "rely" will turn into "reliable".
