Basic spelling rules to know
1. The letter "q" is always followed by "u" and then a vowel.
e.g: quarter, queen, quiz, antique, require, quote.
2. "i" before "e", except after "c" and when it sounds like "a".
(a) I before E
This is usually when the word has the long ë sound as in "piece" e.g: niece, believe, cashier
(b) Except after C
e.g: deceive, ceiling, receive.
(c) When it sounds like A
e.g: weigh, neighbour, beige.
There are some exceptions to the rule:
e.g: ancient, efficient, sufficient, eight, vein, weird, height, weird.
Common suffixes and their meanings
A suffix is a part of a word added at the end to change its meaning or type. Suffixes can turn nouns into verbs. Here's a simple table illustrating some common suffixes and their meanings:
