Is the word doable in there as the form of the word do in an online dictionary, if so which one is it?

Just type the word in Google and see what comes up.

“the form of the word do?” What does that mean? You should regard doable as a contraction of “can be done”.

But it’s not a contraction. It is a yuppy made up word, like “Let’s do lunch some time.” It’s slang

All words are “made up”. This one is assuredly destined for the dictionary if not already ensconced. It’s just too handy. And slang or not, like the infamous “ain’t”
it is a contraction, though this time of a phrase or clause. I wonder. Do you think texting forced doable on us?

I always thought that doable was NSFW.

that too. But it is an expression that creeped into popular usage sometime within the last 20 years? We need to poll the kids here on their awareness of doable. I ask anyone who knows how to enlist Mariah’s attention to this question to do so. The penguin and Jeruba should be in on this one as well.

Come to think of it, maybe it isn’t a contraction, but rather the combination of do and able. Does elimination of the space between the words qualify doable as a contraction?

No, it’s not a contraction but you“re right on the two words it is formed from. It’s really a portmanteau and I would think it definitely predates textspeak.

And here’s a link that dates its usage to the mid-15th century.

O great penguin, goddess of words, is an apostophe required to qualify a word as a contraction?

I haven’t checked but it’s still not there in the printed version? That’s surprising!!!

My 1999 Concise Oxford English Dictionary lists Doable under Do, as a derivative.

Maybe the dictionaries you are looking in just aren’t particularly complete.

I don’t think “doable” is a modern term at except, except possibly in the lewd sense, or in how commonly and annoyingly it is (over)used.

Here is the definition at dictionary.com. If you click the link for “done”, it takes you to a definition of do.

@flo I don’t know if doable is in print. However it is lookupable online. With definition.

Edited to add:
Thanks all. The thing is, what are the online dictionary people thinking by not putting all the forms of a word right there, after defining the main form of the word. Why don’t they have a link forms of the word do instead of the link origin of the word which gives you late Middle English? That is not helpful to people who just want to learn English as a second language.

A contraction is where we slur two consecutive words together ommitting letters but put the apostrophe in place to stand in for the omitted letters.
Can not becomes can’t. The apostrophe stands in for the omitted “O”
“Do able” isn’t a contraction in that sense. You can’t use “Do” and “Able” side by side in a sentence.

It’s an adjective derived from the verb. It’s similar to driveable and understandable.
