Stupid English Tricks by KlionskyG

Sum of the parts, part I
I've got some good questions lined up for you. Let's start with this:

Take a certain common English word (arguably more common in the UK than the US). Remove its final four letters and it's pronounced the same as if you hadn't removed the letters. What's the original word?

Two letters, part I
What is the only English consonant that can be followed by exactly seven different letters to form a valid two-letter Scrabble word (according to the standard Tournament Word List (TWL) dictionary)?

Two letters, part II
Bet you can't name the only English word with three consecutive pairs of repeated letters! If I'm wrong, type it in here:

Alphabet games, part I
Provide two words (minimum two letters each) that are pronounced the same as each other but share no letters in common.

Sum of the parts, part II
CDC? Give a common two-word proper noun containing the letter C three times, each occurrence of which is pronounced differently (at least in standard American English).

Adding an S, part I
Often, adding an S to the end of an English word turns it from singular to plural.

Identify a word wherein adding an S to the end turns it from plural to singular AND makes it refer to something female rather than something male. (Give the shorter word.)

Adding an S, part II
Often, adding an S to the end of an English word turns it from singular to plural.

For what English word longer than six letters is the plural formed by inserting an S as the seventh letter? (Give the shorter word.)

Alphabet games, part II
What is the only number that, when written out in English, has its letters in alphabetical order?

Sum of the parts, part III
A certain common English noun is derived from a Persian word. The spelling of the word in English contains within it the non-overlapping spellings of two other common nouns, each of which could itself be a participant in an instance of the Persian-derived word.

The two shorter nouns have the same length (in letters, if not feet) and are separated in the longer word by a single vowel.

Provide the Persian-derived word.

Consecutive consonants, part I
Easy as pie: give both English words whose pronunciation (but not necessarily spelling) ends with four consecutive consonant sounds, including voiceless fricatives in the final three positions.

(As an aside: These are two of my favorite words for this reason.)

Consecutive consonants, part II
What English word is written (though not necessarily pronounced) with six consecutive consonants? Hasbro opted for a slightly different spelling in their product with a very similar name.

Alphabet games, part III
If GHOTI can be pronounced "fish" (that's GH as in touGH, O as in wOmen, TI as in moTIon), then what common English word does GHOUGHPHTHEIGHTTEEAU represent?
