Sometimes it sounds hard without -y or -ly

The adjective lazy has the adverb form lazily.For most adjectives that end in Y, the Y becomes an i before you add -LY.
In nouns that end with a consonant and Y, the final Y is dropped and the letters ies are added to make the word plural. In words that end with a vowel and Y, the final Y is retained and an S is added, unless that final vowel is a U.
There are no specific rules to be followed for words ending in "ely". Most of the root words ending in E add -ly whereas words ending in Y replace the Y with an I before adding the -ly. Examples: complete => completely icy => icily hungry => hungrily
The adverb is indelibly. Adjectives such as indelible, visible, or arguable already have an L, so add only the Y. Where the L is the last letter (actual, visual), it is doubled by the addition of LY.
It is just an algebraic expression y+3. It means add 3 to y.

No, "Y" is not a suffix. It is often used as a letter in words but does not function as a suffix.
