Does "yar" (or "yarr" or "yargh") in Pirate English imply an affirmative?

Solution 1:

JeffSahol be right, tis usually a placeholder but nay, it be not as 'like' in ValSpeak for tis always an exclamation. Ye hear many a pirate say "Arrr!" meanin' aye, but Long John Silver ere, ee meant it oft times as nay!, as ye may see with yer own pirate eyes and ears in this ere video clip.

Solution 2:

It be like "ano" in Japanese, me boy, or "like" in valspeak, a verbal placeholder.

Solution 3:

"Yarr: v. i. 1. To growl or snarl as a dog." — Webster's Revised Unabridged Dictionary, published 1913 by C. & G. Merriam Co. The top definition on Urban Dictionary agrees.

I think the positive meaning relates to "yare" (Adjective 1. Ready; dexterous; eager; lively; quick to move. Adverb 1. Soon. — Websters). As does this page:

According to the Dictionary of English Nautical Language Database, "yare," also pronounced "yahr" and derived from the Old High German word, "garo," meaning "ready," refers to a well-designed, easy-to-handle boat. "Yar" is also connected to the Gaelic word, "garbh," meaning "rugged," which accounts for the naming of the River Yar on the Isle of Wight.

Solution 4:

I'd be contendin' that 'Yarrrgh!!' would be an affirmation' of yer yabberin'; whereas 'Aaarrghh!' would be refutin' yer spurious claims.

Yaarrrgghh!!
