Is there an English equivalent of the Scots usage of "boak" (meaning retch) as a noun?

"Boak" is a Scots word that means "retch" (or vomit), and like retch it can be used as a verb, i.e. "that makes me want to boak" means "that makes me want to retch", but it can also be used as a noun, as in the phrase "that gies (gives) me the boak", which means the same thing, effectively changing boak from a verb meaning "retch" to a noun meaning "the desire to retch" or "the impulse to retch"

You couldn't say "that gives me the retch" in standard English. Is there an equivalent word that can be used in both ways? Dialect and slang words would be helpful if there isn't a standard English word, but I'd need to know where they are used

Solution 1:

Puke is both verb and noun.

Cambridge

Puke:

noun - vomit

Verb - to vomit

Hence:
He puked after drinking too much and
he left a pool of puke on the ground.

Although it satisfies your title question, it does not work in the more restricted sense you mention of “gives me the boak”, although you might say “… gives me the vomits”, a phrase that is easily found in online search but interestingly is couched in the plural. Nevertheless, vomit is another candidate, being both verb and noun.

Solution 2:

"Makes me gag" is a common expression in English that can be an equivalent of "that gies (gives) me the boak".

The expression has the verb gag meaning "to retch" (make the sound and movement of vomiting). There aren't any senses of noun gag that means vomiting or retching. However, there is gag reflex and you could say "gives me the gag reflex" which is used but not common.

I could smell Southern Comfort around me somewhere, a scent that almost immediately gives me the gag reflex.

The definition of gag reflex from OED:

n. retching, or spasmodic contraction of pharyngeal muscles, esp. triggered by touching structures in the back of the mouth; also figurative.

Additionally, retch is used both as a verb and a noun. The noun usage is not that common. Also, as you said, "gives me the retch" is not used. However, I was curious and I've searched the phrase in Google which only showed two results. (from sources that are not credible).

The definition of noun retch from OED:

An act of retching (in various senses); esp. an involuntary effort to vomit.

The verb retch can have two meanings in this context. The definitions of verb retch from OED:

2.

a. transitive. To expel from the stomach or oesophagus by vomiting. Frequently with up and out.

b. intransitive. To make an involuntary effort to vomit; to strain while making the sound or action of vomiting but without expelling anything from the stomach or oesophagus. Also occasionally: to expel matter by vomiting; to throw up.
