Parseltongue: And how to speak it

Chapter 12: ʃa-words And To help with word order: a mnemonic

Although snakes have not traditionally needed to past from present, they always had a way to distinguish events that will happen from things that already happened. Traditionally, they use this form to give orders instead of to make predictions (although they have come to use the future tense for predictions after interacting with humans). You can express a verb in future tense by changing the ending from 'ʃe' to 'ʃa'; this form of the verb is then considered a ʃa-word.
EXAMPLE:
You will walk to the castle. (Original English)
You castle (will) walk to. (Parseltongue glosses)
Ou vinth vaʃa harne. (Parseltongue)

Note that if a sentence has only one object (including objects of prepositional phrases), the 'subject' means exactly what it does in English while the 'object' is simply the object of the preopositional phrase.
Si-word: You
Subject: You
Na-word: N/A
Ra-word: N/A
Object: castle (This would be "object of a prepositional phrase" in English)
Na-word: N/A
Ra-word: N/A
ʃe-word: (will) walk. (Note that the ending changed to reflect future tense!)
Ne-word: to​.

As a reward for making it through such a tricky lesson, I'm going to teach you a mnemonic to help you remember the rules of Parseltongue word order! It is as follows (presented with dashes between syllables to guide your pronunciation):

​Si-sub-na-ra si-ob-na-ra ʃ​e-ne-suu-sa (esh).

Think of it as follows:
si-word, subject, na-word, ra-word
si-word, object, na-word, ra-word
ʃe-word, ne-word, "word like suu", "word like sa", (ʃ-word) .

(note that suu is a time ne-word, so "word like suu" is a time ne-word; similarly, sa is a yes/no ne-word, so "word like sa" is a yes/no ne-word.)
And that last bit: if you're asking a question, the ʃ-word goes at the very end of the sentence! It appears as "esh" instead of ʃ for a clearer pronunciation.
