Characteristic sequence of letters
In most words like friend, field, piece, pierce, mischief, thief, tier, it is "i" which comes before "e". But on some words with c just before the pair of e and i, like receive, perceive, "e" comes before "i". This can be remembered by the following mnemonic,
But this is not always obeyed as in case of weird and weigh, weight, height, neighbor etc. and can be remembered by extending that mnemonic as given below
- I before E, except after C
- Or when sounded "A" as in neighbor, weigh and weight
- Or when sounded like "eye" as in height
- And "weird" is just weird
Another variant, which avoids confusion when the two letters represent different sounds instead of a single sound, as in atheist or being, runs
- When it says ee
- Put i before e
- But not after c
- Where ever there is a Q there is a U too
Most frequently u follows q. e.g.: Que, queen, question, quack, quark, quartz, quarry, quit, Pique, torque, macaque, exchequer. Hence the mnemonic:
- Where ever there is a Q there is a U too[24] (But this is violated by some words; see:List of English words containing Q not followed by U)

Distinguishing between similar words
- Difference between Advice & Advise, Practice & Practise, Licence & License etc.
Advice, Practice, Licence etc. (those with c) are nouns and Advise, Practise, License etc. are verbs.
- One way of remembering this is that the word 'noun' comes before the word 'verb' in the dictionary; likewise 'c' comes before 's', so the nouns are 'practice, licence, advice' and the verbs are 'practise, license, advise'.[27]
- Here or Hear
- We hear with our ear.

- They're is a contraction of 'they are.'
- Stationary and stationery
- Stationery contains er and so does paper; stationary (not moving) contains ar and so does car[24]

- Gray and grey
- Gray is preferred in America while grey is preferred in England
