"Predominately" is not a misspelling. It's a (much) lesser used form; however, it's standard English, the same as the more widely used form "predominantly."

Also planed is a real word, though most of the occurrences in wikipedia were typos of planned (and in a couple of occasions planet). ϢereSpielChequers 13:26, 20 September 2008 (UTC)
parseable[edit]
Wiktionary lists parseable as a variant spelling of parsable. I feel that parseable should be regarded as non-standard, for the following reasons:
The Oxford English Dictionary (BrE) and the Random House Dictionary of the English Language (unabridged - AmE) both list parsable but not parseable. Most other dictionaries only list parse, with no indication of how to add a -ble suffix to it.
A thorough investigation of words in Merriam-Webster's Collegiate Dictionary ending in -eable finds that they all fall into two categories. One category includes likeable, moveable, useable, etc. They are all equal variant spellings (with likable, movable, usable, etc.) of words formed from verbs that end in a vowel, a consonant, and a silent e. The other category consists of words where the e must be preserved for the sake of pronunciation: peaceable, bridgeable (for soft c and g), malleable, permeable, and seeable (distinct syllables), among others. Parseable wouldn't fall into either category.
Searching Google or Wikipedia for frequencies is not helpful, because both of them do automatic spelling correction and return both spellings in a search for either one. In the past, before this was the case, I found majorities for parsable. More significantly, in both the British National Corpus and the Corpus of Contemporary American English (COCA), there are no occurrences of parseable. Admittedly, it's a small sample: parsable only occurs once in the BNC and twice in COCA.
