I felt more and more tired.
John, with his brothers, was responsible for the loss.

[Frank Antonson]

"More and more" I would treat as a phrasal adverb. It could be replaced by "increasingly".
"With his brothers", because of the commas, is parenthetical. I need to do some more study about how to diagram parenthetical elements. In actual speech, they are very common.

Correct?

Correct?

I would not put "tired" on a step because it is not a gerund but rather a past participle. Actually, I think I would simply treat it as an adjective; but, if it is to be a participle, I would put it on a standard and write it within a 45 degree bend on a line at the top of the standard.
The second sentence I think is right, but I still must look in to parenthetical thoughts.

I know that it is a participle (adj). On second thought, I would simply put it on the base line.

I think that in general if a dictionary recognizes an adjective as such, one shouldn't worry if it derived from a participle.

Sorry to interrupt, but are there diagramming rules or restrictions about word forms at work here? It's functioning here as an adjective so I am not sure about why it might have to be a participle.
(Please forgive my ignorance of diagramming)

[Frank Antonson]

I appreciate the "interruption".
"Tired" does not have to be a participle. In Reed-Kellogg participles are shown by a bended word within an inside corner.
If it were a participle that, like a simple predicate, had complements of some kind, it would be useful do diagram it as such. Here it is unnecessary. Clearly, though, the adjective "tired" is derived from the past participle of the verb "to tire".
Does this make sense?
