"Please" across Languages

I beg

• Polish: proszę/prosimy
  • Seems to have only a slight preference to exist clause-finally. Also fairly common clause-initially.
  • Inflects for number of speaker (singular/plural).
  • Takes an infinitive.

I will love you

• Latin: amabo (te)
  • Since I don't know of any study on this, I will conduct my own (corpus):

    • te amabo: 1 attestation (Pl. Cist. 1.1.100)
    Misc notes:
    • Seems to also be able to be used to request an explanation (reminiscent of the archaic English idiom pray tell):
      • Quid ita, amabo? (Pl. Cist. 1.1)
        • How so, pray tell?
      • Amabo, cuia vox sonat procul? (Pl. Cur. 1.2)
        • Say, whose voice is calling out in the distance?

if it pleases you

• English: please
  • Three valid positions: clause-initial, clause-final, or immediate preverbal. In simple clauses, the first feels by far to be the most common and neutral.
  • Syntactically, this is an adverb and therefore frequently comes between the verb and its auxiliary (or 'to', if infinitive): eg. "Tell him to please stop calling me." and "If you would please turn the computer on, we can begin."
  • Also frequently construed as an interrogative with the modal can/could or will/would: eg. "Would you please not shoot the pigeons?"
  • Clause is otherwise inflected in the imperative mood.
• French: s'il vous/te plaît
  • Seems to have a strong preference to lie at the end of the clause.
  • Inflects to listener, in politeness/number (these categories are somewhat collapsed in French).
  • Clause is inflected in the imperative mood.
