when you aggree with someone or an argument

1. Slightly more ammusing form of indeed.

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."

A cooler, more fun version of indeed only said by the coolest people.

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.

It's basically the same as indeed, only you get to add an extra word after it, to sound more official and cool. Like bow ties. Bow ties are cool.

to be sure or extremely sure
