What part of speech is beyond?

Answer 1

The word "than" is a subordinating conjunction. It is also used prepositionally.

It is used after comparative adjectives and adverbs, such as "greater than", "faster than", "less complicated than", "more slowly than".

Example:

"He is taller than I am." (Can be abbreviated to "He is taller than I." The word "am" is understood.)

Common errors:

"He is taller than me." (Colloquial usage.)

"This coin is different than that one." (American usage. Grammatically, the word "different" is not a comparative adjective. Correct usage is "different from".)

Used prepositionally after a comparator:

"There are fewer than ten people."

"I'd rather e-mail than 'phone."

"Is there a way other than this?"
