Spelling patterns this week: prefixes il-, im, ir
Relevant spelling guidelines: The prefix in- changes when the root word begins with either l, m, p, or r (see below). The prefix still makes the root word negative, and most commonly means ‘not’. The prefix is just added to the root word without a change in spelling.
- Before a root word beginning with l, in- becomes il-
- Before a root word beginning with m or p, in- becomes im-
- Before a root word beginning with r, in- becomes ir-
