As everyone knows, the longer a word is the better it sounds. Thus, when people add senseless suffix's to words, it only makes the English language cooler. Such is the case when dumb, boring words like "indeed" are changed to long, flowing and luxurious words such as "indeedly." In essence "indeedly" is just the cool people's way of saying "indeed."

In agreement, to agree further more and build upon your sentence. It can also be used to make people think you know what you've talking about, even if you do not.

"Bow ties are cool."
"Indeedly so, doctor."
