Adverbials happen to be the thing this challenge is about.

There are five types of subordinate clauses in English: the subject, the predicative, the attributive, the object and several types of adverbial clauses.

In English grammar, all the clauses are subdivided into three main groups: noun clauses, adjective clauses and adverb clauses.

The Noun clauses include three types of subordinate sentences such as the subject clause, the predicative clause and the object clause. Usually in subordinate clauses we use the direct word order but in some cases we may face a particular version of inversion. Also, different subordinate clauses need to be introduced by different introductory words which cannot be omitted.

Try the challenge to figure out what all this is about!

Subjunctive mood is represented by three main forms in contemporary English: present subjunctive, past subjunctive, past perfect subjunctive. Other forms such as present continuous subjunctive and past continuous subjunctive are used very rarely.

Apart from the aforementioned, advanced students are particularly interested in the accurate usage of such verbs as should, would, could, might, wish after if and in the case when it is omitted in the mixed type conditionals.
