For making comparative forms of adjectives, we add “more” before adjectives with more than one syllable and other than those two-syllable adjectives ending in “y”. So for example:
“This watch is more expensive than yours.”
And for other adjectives we add “-er” to the end of the adjective. So:
“He is healthier than his wife.”
In both above examples, the comparatives help to convey that the subject is at the higher level about the mentioned adjective: “The price of this watch is higher than yours.”
How we can convey the meaning that the subject is at the lower level than another thing? For example:
“Regarding his health, he is worse than his wife’s condition.”
If I want to rearrange the above sentence, is the following sentence grammatically correct?
“He is less healthy than his wife.”
And if the above sentence is grammatically correct, should we use “less” for all kinds of adjectives? I mean one syllable or more than one syllable? For example is the following sentence grammatically correct?
“It is less cheap than that one.”
