would you be kind enough to tell me whether i am right with my interpretation of the expressions in bold in the following sentences?
“i slept in and had to pack my bag in a panic. “
sleep in = oversleep, sleep late yes
“if a child threw a fit in a shopping mall, it would be correct to say, “she behaved badly.””
throw a fit = have a fit = become extremely upset.; make a scene (make a row) yes. Also "chuck a wobbly". in a child it is usually called a "temper tantrum"
fit and fits, along with conniption fit, have been used in hyperbolic expressions to denote a bout of hysterics. yes, but "to have a fit" often means to have an epileptic fit, not a fit of anger, etc. "throw a fit" is better for the emotional context.
“this is not a hard-and-fast rule, however; such mass nouns as furniture and cutlery, which represent more easily quantified objects, show that the mass/count distinction should be thought of as a property of the terms themselves, rather than as a property of their referents.”
hard-and-fast rule= very strict used rule. yes, otherwise called a rule that is "set in concrete."
thank you for your efforts.
