This page details the grammr of Plasper. It's pretty easy to learn.
Words ending in 'ing' (such as running, hitting, smashing, but not string, fling, bring) will have the letter 'ë' on the end. For example, novight (place), novightë (placing).
Words ending in 'ed' (such as ruined, straightened, but not bred, fed) have the letter 'ä' on the end. For example, icasci (eye), icasciä (eyed).
Words ending in 'er' (such as painter, rustler, but not butter, steer, tier, hamburger) have the letter 'ö' on the end. For example, insuchi (low), insuchiö (lower).
Words ending in 'est' (such as highest, greatest, stupidest, but not pest, incest, crest) have the letter 'ü' on the end. For example, robjpe (fine), robjpeü (finest).
Plurals end in 'ï'. For example, ffegow (physician), ffegowï (physicians).
Some contractions are written in a vastly shorter way: Couldn't (c'), don't (d'), wouldn't (wd'), won't (wo'), shouldn't (sh'), aren't (a'), can't (ca'), hasen't (ha'), hadn't (hd'), doesn't (do'), didn't (di'). The rest are written the same in Plasper, but the apostrophe is moved to the end: Ain't (aint'), shan't (shant'), I'd (Id'), he's (hes'), she's (shes')
Words which can have the 'ence', 'ary', 'cian', 'tion', 'sion' or 'cion' suffix will end in said suffix. For example, dselep (sense), dseleption (sensation), eicieti (electricity), eicietician (electrician), ctedss (affect), ctedsstion (affection).
Words which can be made into adverbs by having a suffix (-ally, -ly) on the end will end with the suffix. For example, umushex (careful), umushexly (carefully).
Words with the un-, in- or -ir prefixes start with 'ï'. For example, troouc (certain), ïtroouc (uncertain).
Words with the re- prefix start with 'ä'. For example. ivenno (made), äivenno (remade).
Words with the over- prefix start with 'ö'. For example, onsibap (time), öonsibap (overtime).
Words with the under- prefix start with 'ü'. For example, ckansys (act), ückanskys (underact).
A sentence in English is written the same way in Plasper. The only difference is that the words are translated. For example: 'The school was small' translates as 'Owavel (The) ooduldr (school) ondepti (was) opsnove (small).'
All one and two letter words in English are not translated. This also includes two-letter words with plurals (its stays as its).
Punctuation stays the same.
To help shorten sentences, the following words are one lettered: The (ë), and (ä), of (ö), it (ï).
Words which have the prefix 'co-', such as 'cooperate' and 'cocaptain' will start with 'u-'. For example, ducinb (operate), u-ducinb (cooperate)
