Editing Clause (section)

===Verb first clauses===
Verb first clauses in English usually play one of three roles: 1. They express a yes/no-question via [[subject–auxiliary inversion]], 2. they express a condition as an embedded clause, or 3. they express a command via imperative mood, e.g.

::a. He '''must''' stop laughing.{{Snd}} Standard declarative SV-clause (verb second order)
::b. '''Should''' he stop laughing?{{Snd}} Yes/no-question expressed by verb first order
::c. '''Had''' he stopped laughing,&nbsp;...{{Snd}} Condition expressed by verb first order
::d. '''Stop''' laughing!{{Snd}} Imperative formed with verb first order

::a. They '''have''' done the job.{{Snd}} Standard declarative SV-clause (verb second order)
::b. '''Have''' they done the job?{{Snd}} Yes/no-question expressed by verb first order
::c. '''Had''' they done the job,&nbsp;...{{Snd}} Condition expressed by verb first order
::d. '''Do''' the job!{{Snd}} Imperative formed with verb first order

Most verb first clauses are independent clauses. Verb first conditional clauses, however, must be classified as embedded clauses because they cannot stand alone.
