Verb conjugation is a method of changing verbs from their infinitive forms. The changes, usually done through endings and auxiliary words, express grammatical categories related to the action or state being described, such as person, number, tense, aspect and mode. Verbs are divided into a number of classes according to their form of conjugation and may be assigned model patterns to help to create the correct forms.
There are simple verb forms (e.g. ich mache, ich machte) and compound verb forms that use an auxiliary verb (e.g. ich habe gemacht, ich werde machen).
There are 6 tenses in German in total. Two of them are simple: the present simple (Präsens) and the past simple (Präteritum). The other four tenses are compound, i.e. they combine an auxiliary verb and the infinitive or the past participle form of the main verb carrying the meaning. The compound tenses include the future simple (Futur I), the present perfect (Perfekt), the past perfect (Plusquamperfekt) and the future perfect (Futur II).

Subjunctive of verb of the regular verb [tasten]
The subjunctive (from the late Latin modus coniunctivus, translated as a form of sentence structure, derived from the Latin verb coniungere – to join).
The subjunctive is a special verb form that usually expresses that the action is conditional or hypothetical.
It expresses possible, probable, hypothetical, desired, dreaded or necessary actions (thus indicating the speaker’s attitude toward the action). It is a form used to express something imagined that may never happen. In particular, it marks the utterance as subjective, doubtful or uncertain.
In German, there is the subjunctive I and the subjunctive II.
The subjunctive I includes the present subjunctive (e.g. er sei, er habe), the future subjunctive and the perfect subjunctive.
The subjunctive I usually expresses someone else’s opinion, often unlikely from the speaker’s point of view (present indicative: Er sagt, dass niemand zu Hause ist. – He says that no one is at home. X present subjunctive: Er sagt, dass niemand zu Hause sei. – He says that (supposedly) no one is at home.).
The subjunctive II includes the past subjunctive (er wäre, er hätte) and the past perfect subjunctive.
