Hello,
What’s the difference between “suck sth”, “suck at sth” and “suck on sth”?
Thx
You can look up “suck” as is suck something. Here is a good site: dictionary.reference.com/browse/suck I think the most common definition is " to apply the lips or mouth to and draw upon by producing a partial vacuum, especially for extracting fluid contents"
“Suck on” is basically the same thing, though for “suck on”, I think this definition is more common: “to take into the mouth and dissolve by the action of the tongue, saliva, etc.:
to suck on a lollipop.”
“Suck at” is a slang phrase and means to not be very good at something.
