A verb is conjugated interrogatively in the indicative and the potential mode by placing the subject after the first auxiliary word in the verb phrase. If the verb phrase is only a single word, do or does is added for the present tense and did is added in the past tense.

For the potential mode, can is added as a first word in the verb phase.

• INDICATIVE MODE

  Do I love?
  Have I loved?
  Did I love?
  Had I loved?
  Shall I be loved?
  Will they have loved?

• POTENTIAL MODE

  Can I love?
  Can I have loved?

A verb is conjugated in the negative by placing the adverb not after the first auxiliary. If there is no auxiliary, the auxiliary do, does, or did is added. In the case of an infinitive or a participle, not is placed before the whole verb.

• INDICATIVE MODE

  I do not love, or, in an older style I love not.
  I have not loved.
  I did not love or I loved not.
  I had not loved and so on.

• INFINITIVE MODE

  not to love
  not to have loved

• PARTICIPLE FORM

  not loving
  not loved
  not having loved

A verb is conjugated interrogatively and negatively in the indicative and the potential mode by placing the subject and the adverb not after the first auxiliary of the verb phrase. If there is no first auxiliary, the correct form of the auxiliary do is added.

For example

Do I not love?
Have I not loved?
Did I not love?
Had I not loved?

Note

In current usage, most negative verb forms for questions are created using contractions as Don’t I love? or Didn’t I love? instead of the following correct but older forms.
Do I not love?
Have I not loved?
Did I not love?
Had I not loved?
