I am having difficulty diagramming this sentence.
Parents chose to hide the learning disability with medication.
I know parents is the subject and chose is the transitive verb. I am not sure where the rest of the sentence goes.
May I try? I shall use the traditional names for the parts of speech. I shan't be using the new terms, such as "determiner," "adjunct," etc. Somebody who understands those terms may help you later.
(1) I think you need a possessive adjective in front of "parents," such as "their," "his," her," "my," etc.
(2) My parents = complete subject (my = adjective; parents = noun; simple subject is "parents").
(3) chose to hide the learning disability with medication. = complete predicate. (a) "chose" = simple predicate (b) to hide the learning disability with medication. = infinitive phrase that is the object of "chose."
(4) to hide = infinitive; the = adjective (or just "article"); learning = participle being used as an adjective; disability = noun; with medication = prepositional phrase that modifies (belongs to) "hide"; with = preposition; medication= noun (the object of "with").
(You) have a nice day! (I) thank you.
