Sorry, Justine, it must be due to the oppressive heat in my room at mid-morning today (the aircon was just starting up, you see). In Item 2 of my response to you, the statement "Subjunctive using
the infinitive phrase 'to demand that...' as direct object of the verb 'wrote'" should have correctly read "Subjunctive
using the gerund phrase 'demanding that...' as direct object of the verb 'wrote'." I copy-pasted the statement from Item 1 but overlooked changing "infinitive phrase" to "gerund phrase." My apologies. (I am correcting the post right after this to avoid confusing others.)
Now as to this post that you came across in Facebook: "When everything seems wrong, look and be with nature's perfect GOD creations to make everything feels right." You got the wrong impression that the use of the linking verb "feels" is in the singular form because the sentence is in the subjunctive form. Actually, the verb "feels" is not a linking verb in that construction, and nor is the sentence where it appears in the subjective mood. In fact, "feels" should be corrected to "feel" but not for subject-verb agreement but for an entirely different purpose.
In the corrected verb phrase "to
make everything
feel right," the verb form "make" is what's known as a
causative verb, which is a special kind of verb that carries out an action that causes another action, state, or condition to happen. Specifically in this case, "make" is the causative verb that causes the condition "feel right" to happen.
For a much better understanding of how causative verbs work, check out the two essays that I have posted in the Forum,
"Using causative and factitive verbs," and
"How the causatives enable intransitive verbs to overcome their intransitivity." I'm sure that those two essays will throw an entirely new light to some strange grammatical constructions that must have intrigued you in your readings.
