[1] In the Niger-Congo language Supyire, the form of the first person and second pronouns reflects whether the clause has declarative or non-declarative mood.
In the Gǀwi language of Botswana, subject pronouns reflect the imperative or non-imperative mood of the clause (while the verb itself does not).
In the Chamicuro language of Peru, the definite article accompanying the subject or object of a clause indicates either past or non-past tense.
In the Guarani language of Paraguay, nouns can optionally take several different past and future markers to express ideas[2] such as "our old house (the one we no longer live in)", "the abandoned car", "what was once a bridge", "bride-to-be" or even "my ex-future-wife," or rather, "the woman who at one point was going to be my wife."
Another way to tell the difference is to consider the following hypothetical dialogue: The speaker cannot emphasise the future time by placing voice stress on she'll, and so instead uses the expanded phrase she will.
