The Spelling <rr> and Assimilation

1. Here are the twenty words from the previous lesson that all contain <rr>:

irrigationoverripereferredarrestarrivalinterruptconferringscarredcorrectlycorruptionirritatepreferredarrangeirregularcorrespondunderratedtransferringirresponsiblesurrenderedsurroundings

You have seen that five of these twenty words have <rr> because of simple addition and five of them have <rr> because of twinning. Find these ten in the list above and cross them off.

2. When the prefixes ad-, com-, and in- are added to stems that start with an <r>, they assimilate to _______, _______, and ______.

3. Ten of the twenty words above with [r] spelled <rr> start with an assimilated form of ad-, com-, or in-. Find them, write them in the left column below, and analyze them to show the assimilation that leads to the <rr>:

Word Analysis: Prefix + Stem
irrigation in + r + rigation

4. The following words each contain two prefixes and a stem. See if you can analyze them to show where the <rr> comes from:

Word = Prefix1 + Prefix2 + Stem
incorrect = + +
rearrange = + +
unirritable = + +
overirrigated = + +
noninternational = + +
uncorrupted = + +
rearresting = + +
nonsupportive = + +
disarranged = + +
irresponsibly = + +
unsurprising = + +
