But where if it locates our bigger difficulty in relation to the use of hifens? As much in the New Agreement as in the previous rule, the biggest same problem seems to be focado in on words with some types of prefixes and not in relation to the composed words. I explain: Amongst some consideraes on the formation of the words, basically we find two processes: composition or derivation. The composition happens when the word is formed by two radicals (two units of meaning, ' ' razes' '). Already the derivation estimates, in the majority of the cases, that has on prefixes or suffixes to a radical. Thus, a word that has prefix does not mean that it is composed. The prefixes are annexed simple units before the radical: ' ' pr' ' = ' ' daily pay-escola' ' , ' ' daily pay-datado' ' , ' ' daily pay-vestibular' ' etc. What it occurs is that it has other prefixes that possess one ' ' cara' ' a little stranger, that is, they are looked like words. It is the case of ' ' semi' ' , ' ' supra' ' , ' ' infra' ' , ' ' auto' ' , ' ' contra' ' , ' ' extra' ' , ' ' ultra' ' etc.

As we will need to understand well these prefixes to understand the new rules, I give a tip to know to them to recognize them. It uses word S U P I N AND C. In it, we can remember to us of the main prefixes: S U P I N AND C half the extreme infra pseudo neo extra against auto supplies intra anti Observe that I joined, above, a considerable parcel of prefixes that finish in vowels. It has, evidently, others that have the termination in consonants as ' ' hiper' ' , ' ' circum' ' , ' ' pan' ' , ' ' sub' ' etc.
