Some examples for free morphemes include dog, cow, dish, yes, ship, event, run, eat etc. However keep in mind that, not all free morphemes can be considered as words.

Bound morphemes are the morphemes that cannot stand alone. They appear only as parts of words, and when used alone, they do not have a meaning. Most bound morphemes in the English are affixes. They can be used before or after the base word. Base or a root is a morpheme in a word that gives the word its principle meaning. The affixes that come before a base are called prefixes. The affixes that come after a base are called suffixes.

Phonemes are put together to create morphemes and words. The main difference between a morpheme and phoneme is that while a morpheme carries a meaning, a phoneme itself does not carry any meaning. It is merely a unit of speech.

The difference in meaning between two words can be because of a single phoneme. For example, take the words, cat and cut. There are both vowel phonemes and also consonant phonemes.

There are often numerous graphemes or phonograms that can represent a single phoneme. While English has 26 letters and 44 phonemes, there are approximately graphemes. Perhaps the most neglected term and concept in the study of teaching reading is the morpheme. A morpheme is the smallest unit of meaning that cannot be further divided. So, a base word might be a morpheme, but a suffix or prefix or root also represents a morpheme.

While none of these units stand alone as words, they are the smallest units of meaning. Morphemes can vary tremendously in length from a single letter such as the prefix a- to a place name derived from another language such as Massachusetts, which in English represents a single morpheme. As students move into reading and writing more sophisticated academic language, the concept of morphemes becomes increasingly important to their decoding and their spelling as well as their ability to infer meanings of new vocabulary.

The root of a word makes tremendous differences in spelling words with the -ion suffix for instance. While linguists can spend hours debating the precision of certain aspects of morphology such as whether the word dog is made of one morpheme or 2 the base word and the absence of a suffix or nul , the purpose of our pursuit of this study is far from a purely cognitive exercise. The reason for building this understanding is clear. English is by its nature a morpho-phonemic language.

Not only is it phonemic in nature, but morphology also has a crucial role to play as well. In addressing both aspects of language learning, give your students the tools to understand the challenges of words that change pronunciation with the application of affixes such as clean and cleanse or sign and signature. Try to help them to understand seemingly random spellings like to and two when they learn about the relationship of two to twenty and twin and twelve.

English makes sense!
