Signalers¶

Nouns¶

Can show plural
Can show possessive

Verb¶

Can show tense, such as present or past

Complements: Note¶

Simple grammar labels roles by meaning or surface pattern (e.g. “linking verb,” “object complement”), while CGEL defines them strictly by syntactic selection and head–dependent relations. So something counts as a complement in CGEL only if it is selected by a head; otherwise—even if it feels semantically important—it is analyzed as a determiner, modifier, or adjunct.

Adjective Complements¶

(phrases completing the meaning of an adjective)

Common Signalers	Examples
Prepositions (often of, with, about, to, at, for) Subordinators introducing clauses (that, if, whether, how, why)	afraid of spiders happy that* you came* keen to help

Subject Complements¶

(occur after linking verbs)

Common Signalers	Examples
Linking verbs: be, become, seem, appear, feel, look, remain, sound, stay, taste, smell, grow, turn	She is a teacher. He became* angry.* The milk smells* bad.*

Object Complements¶

(complete or modify the object)

Common Signalers	Examples
Causative/perception verbs: make, find, consider, call, elect, name, paint, leave, choose Verb + object + infinitive/adj/noun patterns	They made me angry. We elected her president. I found the movie boring.

Try to change the verb:

Only certain verbs allow this pattern:

✔ leave the door unlocked

✖ admire the door unlocked

The availability of unlocked depends on the lexical properties of leave. That dependence is a hallmark of complements, not adjuncts.

Main signalers of implied subjects¶

Structure Type	Signalers / Clues	Implied Subject Is…	Example
Imperatives (commands/instructions)	Verb in base form with no stated subject	You	Sit down. → (You) sit down.
Infinitival clauses (to + verb)	“to + verb” without a stated subject	Usually the subject of the higher clause, or generic “you/one”	I want to leave. → (I) want (me) to leave.
Gerund clauses (verb-ing phrases)	-ing form functioning as subject/object without explicit subject	Often generic “you/one” or contextual agent	Swimming is fun. → (People / you / one) swimming is fun.
Diary / note style (elliptical clauses)	Present tense verbs without subjects in informal logs or headlines	I (first person implied)	Feeling tired today. → (I am) feeling tired today.
Instructions / Recipes / Headlines	Telegraphic style lacking subjects	Generic one / you / we / people	Add water. Bake for 20 minutes.
Subordinate clauses used as complements	Verbs like want, know, hope, decide followed by to + verb	Same as subject of main clause	They decided to leave. → (They decided (they) would leave.)
Non-finite clauses after prepositions	before/after/by/without + -ing	Contextual doer from main clause	She left without saying goodbye. → (She left without her* saying goodbye.)*

Transitive Verbs¶

Probably an Object.

A complex transitive verb that selects two complements, signals an Object complement:

Chocolate makes [her] [happy]

Intransitive Verbs¶

A verb that does not take a direct object.

The next element, if anything, is likely to be an adjunct
