Online Technical Writing: Spelling Problems
This section covers the most common conventions—or rules—concerning grammar, usage, and punctuation. It also discusses how to handle numbers, abbreviations, and symbols in technical writing. The discussion of the various problems or errors in this section uses the terminology explained in the section on sentence structure and patterns. If any terms, such as object complement or antecedent, are unfamiliar to you, go to that section.
If you have problems with spelling, they may only be a few specific areas that you can overcome once you identify them and practice a bit. The sections in the following review some of the most common areas of spelling problems.
For some writers, their main spelling problem is similar-sounding words, for example, principle and principal or affect and effect. Here is a list of these commonly confused homonyms, with examples of their correct use.

Doubled internal consonants
Many words double internal consonants while others do not: for example, recommend, accommodate, and committee. Try memorizing these in contrasting pairs (recommend and accommodate, for example).
Internal syllables or letters
Many words have short, practically unpronounced internal syllables that are easily omitted or misspelled: for example, athletics, category, disastrous, optimistic, privilege, and desperate. Perhaps the only way to learn these is to repeat them several times, emphasizing the internal syllable: for example, ben-EH-fi-cial, bound-AH-ries, cat-EH-go-ry.
Words with endings such as -ance and -able
Another source of spelling difficulties is words with similar-sounding endings: extravagant, occurrence, compatible, irresistible, and performance.
Words ending in -sede, -ceed, and -cede
Still another group of confusingly spelled words is that group ending in -sede, -ceed, and -cede: for example, precede, proceed, exceed, supersede. Again, the best thing to do is memorize them or look them up.
The groups of words discussed above are by no means all of the possibilities. You may have trouble with words ending in -or and -er or those ending in -ary, -ery, and -ory. Make your own lists of such word groups that give you problems in spelling.
The silent -e rule
When words end in a silent -e (for example, write), you drop the -e when adding a suffix (write + ing = writing), except when the suffix begins with a consonant (excite + ment = excitement).
The rule for -ie and -ei
Use i before e except after c in words in which the sound is a long e (as in "feet") in words such as piece, receive, and fiend. There are exceptions to this rule: leisure, either, weird, and seize.
When you add a suffix to a word ending in a consonant, make sure you know whether to double the final consonant: drag becomes dragged, but equip becomes equipment.
Words ending in -y
When adding a suffix to a word ending in -y, make sure you know whether to change the y to i: enjoy becomes enjoys, but try becomes tries.
