From aelfheld in the previous post, here's another: people who confuse "phase" with "faze." Here are the definitions of both:

Phase:

–noun
1. any of the major appearances or aspects in which a thing of varying modes or conditions manifests itself to the eye or mind.
2. a stage in a process of change or development: Each phase of life brings its own joys.
3. a side, aspect, or point of view: This is only one phase of the question.
4. a state of synchronous operation: to put two mechanisms in phase.
5. Astronomy.
a. the particular appearance presented by the moon or a planet at a given time.
b. one of the recurring appearances or states of the moon or a planet in respect to the form, or the absence, of its illuminated disk: the phases of the moon.
6. Zoology. color phase.
7. Chemistry. a mechanically separate, homogeneous part of a heterogeneous system: the solid, liquid, and gaseous phases of a system.
8. Physics. a particular stage or point of advancement in a cycle; the fractional part of the period through which the time has advanced, measured from some arbitrary origin often expressed as an angle (phase angle), the entire period being taken as 360°.
–verb (used with object)
9. to schedule or order so as to be available when or as needed.
10. to put in phase; synchronize: to phase one mechanism with another.
—Verb phrases
11. phase down, to reduce by gradual stages.
12. phase in, to put or come into use gradually; incorporate by degrees: to phase in new machinery.
13. phase out, to bring or come to an end gradually; ease out of service: to phase out obsolescent machinery.
Origin:
1805–15; (n.) back formation from phases, pl. of phasis

Related forms:
phaseless, adjective
phasic, pha⋅se⋅al, adjective

Synonyms:
1. form, shape; facet, side.

And:

Faze:

–verb (used with object), fazed, faz⋅ing.
to cause to be disturbed or disconcerted; daunt: The worst insults cannot faze him.
Origin:
1820–30, Americanism; dial form. of feeze

Synonyms:
disconcert, discomfit, perturb, fluster, confound.

A person could be "going through a phase" that causes them to become "fazed." See, that's how you use it. They are not interchangeable. Spell them right! Or else.

I found this somewhere on the internet, can't remember where now: someone had used the word "bought" when they clearly meant "bout." "Bout" refers to a period of some sort of activity or state: a bout of fighting, a bout of hunger, etc. It's not used much anymore (like so many useful words), so it's not surprising that people would automatically type in "bought" (the past tense form of "buy").

The word "whack" does not have an adjectival version ending in "y" and meaning "crazy" or "silly," as is seen in this blog comment. The word wanted is "wacky." Note the spelling -- "w" is used, not "wh." (Careful speakers would pronounce the two words differently -- "wh" is unvoiced while "w" is voiced -- but today it's becoming increasingly rare to find people who pronounce "wh" and "w" differently.) "Whack" is a verb meaning "to strike" or "hit." Now don't misuse these two words anymore or I'll whack you in the head until you're wacky.

When you mean to use "yoke" to refer to something burdening or controlling a person, do not spell it "yolk," which is the yellow part of an egg. An example of this common mistake can be seen in the comment I quoted here.

I'm going to give this commenter the benefit of the doubt and hope he meant "execrable" instead of "excretable" in this passage:

In fact, graying hipsters telling 20-somethings how excretable ABBA or Pat Benatar or ELO was just drives them a bit further to load those tunes up on their iPODs.

Of course, many people considered the output of the above-named artists to be comparable to feces, so perhaps "excretable" was carefully chosen after all.
