I once had a discussion with some of my friends at school about something that is not really referred to by most grammar literature as it is about incomplete sentences/clauses. I'll give you some examples:
- "Add WiFi-Network"
- "Select language"
Those are options given in the settings menu of all of our phones. When analyzing the verb form nobody could not really identify what it is. One argued that it is an imperative (towards the phone) and therefore it is actually some kind of a complete sentence. Another believed in an infinitive. Another one argued that isolated infinitives always carry a "to" and therefore he opposed the idea of an infinitive in the examples given, although German, Spanish and French clearly use infinitives on these occasions. I believe that due to the need of short constructions the "to" is simply dropped but I cannot give them any proof.
Can somebody clarify the situation?
Thanks to all of you in advance.
