Meaning
What is this word's meaning and how does the word function?
What does it mean to be covetous? Immediately, I'm taken back to my childhood and memorizing the Ten Commandments:
"Thou shalt not covet thy neighbor's wife."
I may use a Fist to Five strategy to elicit my student's knowledge of a word.
fist-I don't know this word
one finger-I've heard this word.
two fingers-I've heard this word, and I think I know what it means.
three fingers-I know what this word means.
four fingers-I know what this word means, and I can give you a sentence.
five fingers-I could teach someone this word.
Any time my student gives me a one or two, I might try to elicit some of their knowledge. For me it was the Ten Commandments; it might be different for someone else.
The official definition, according to the Collins dictionary, is "a strong desire to possess something, especially if it belongs to another person."
So the commandment is telling us we shouldn't want our neighbor's wife because it belongs to our neighbor. It's not just about the wife, but the sense of possession hasn't aged well in that translation.
I'm reminded of phrases like "keeping up with the Joneses." I think of how when one neighbor mows their lawn, everyone is always out there later that afternoon or the next day. Unfortunately, I'm often the one with the shaggy lawn everyone is staring at the next day. No one coveting my landscaping skills here.
This word has an adjective form. Adjectives can be inflected for degree. In some cases, we do this with the suffixes <-er> and <-est>, as in bigger and biggest. In other cases, as with covetous, we do it with more and most, more covetous and most covetous.
We can also use a syntactic test to determine if the word is functioning as an adjective. A syntactic test may involve a frame where we can situate a word. For adjectives, the following frame may be used:
The X man is very X.
I could substitute my word for either X. The frame works because true adjectives can modify nouns like manand stand alone after linking verbs. If it makes sense, it's likely to be functioning adjectivally.
The tall man is very tall.
Yes, tall is an adjective here.
The kitchen man is very kitchen.
No, kitchen is not an adjective here.
The delivery man is very delivery.
Hmmm...in the first slot, it seems this way. Certainly, delivery is modifying man, but it doesn't make sense in the second slot. We also can't say a man is more delivery or most delivery. Nouns can function adjectivally to modify other nouns. This doesn't make them an adjective per se.
The covetous man is very covetous.
This makes sense, so covetous is functioning as an adjective here.
