The prefix ir is an interesting prefix for a number of reasons:
1. It means not. There are many prefixes that can mean not, such as de, a, un, non; however, ir also means not, which is interesting to me because I don’t think it sounds like it should mean not! To me, it sounds like it should mean again or repeating or something besides not!
2. It only comes before base words that begin with R. In other words, you do not put ir in front of most any word to mean not, like you often do with un or non.
3. This isn’t really interesting–but I like to say it whenever I teach about prefixes. A prefix is a letter or group of letters that you “affix” (which is why it and suffixes are called affixes) to the beginning of a word. It is important to remember that a prefix does not change the spelling of the base word. That is especially crucial in spelling ir words because the ir precedes an R already–and you must keep the base word’s spelling, so when you add this prefix to a word, you will ALWAYS have two R’s in a row: irregular, irresponsible, etc.
4. It is most often put before a word that is should never come before: regardless. We hear people constantly say irregardless, which is, of course, an oxymoronic word because less means without (or not) and ir means not. I guess that makes it sort of like using a double negative! You do not put ir before regardless because regardless already means without regard. With ir in front of it, you are saying not without regard, I guess…. Anyway, irregardless is not a word. So don’t use it. Okay? 🙂
Note: It is correct, however, to use irrespective, which is a substitute (some of the time) for when you are tempted to say irregardless.
However, there are many base words that begin with R that can have ir put before them to mean NOT or the opposite of what the base word means before ir is added to it.
Here is a list to get you started. Notice how if you take the ir off, you have a positive base word (or one that means yes–yes regular, yes responsible, yes revocable, etc.) However, with the ir, the word means not—not regular, not responsible, not revocable, etc.
Remember: You know more than you think you know!
And remember: Use what you already know to learn even more!
We are having a heat wave here in Indiana. We have had temperatures above ninety degrees this week. Today it was 92 degrees–a perfect day to go swimming and a perfect day to get a sunburn!
For today’s WORDY WEDNESDAY, I thought we would look at two prefixes that have to do with July in Indiana–SOL and THERM.
If you have been reading Language Lady very long, you know my two rules of thumb for learning:
1. You know more than you think you know.
2. Use what you already know to learn even more!
Those two rules of thumb definitely apply to today’s prefixes.+
We encourage our students to take a key word–any word that you already know–that has to do what you are trying to learn.
In the case of sol and therm, you can take two words you already know as your “key words” to help you remember these two prefixes:
SOL–solar….you know that solar means sun if you have ever talked about a solar blanket for your pool, solar power (generating power through the sun), or solar eclipse
THERM–thermos or thermal…you know that THERM means heat if you have ever carried your soup or coffee in a thermos or had “thermal underwear” on in the winter to keep you warm.
So…take your two KEY WORDS and use them any time you see the prefixes SOL and THERM:
b. solarium–part of a room that is exposed to the sun
c. solstice–the pointer in which the sun stands sill
The “solar heat” is high right now in Indiana, and the thermometer shows it at in the low nineties!
+Remember: A prefix is an affix. An affix is a letter or letters attached to a word that give more meaning to the word. The affix itself actually has meaning. A prefix is an affix that is added to the beginning of a word–thus, the prefix to the word prefix PRE (meaning before)!
When Joshua and I teach vocabulary, we try to do a few things:
1. Relate the word to anything we think the students might already know. (“Aquaduct? Well, you know what aquatic means, don’t you?”)
Of course, this is where we say, “You know more than you think you know!”
2. We ask the students if they can tell us anything about the word based on the context. Is it happy or sad? Is there a word near that word that helps you?
3. We help them examine the type of word it is. We say over and over to them that OUS words are often adjectives (delicious) and ATE words can often be verbs.
4. We help the students examine roots and affixes.
a. Prefix–an affix (“stuck on”) to the beginning of a word
b. Suffix–affix added to the end of a word
We also give the students tools all the time. Below is a list of prefixes and suffixes that we give to our students and discuss with them, along with their meanings.
