Mindful Zen of Morphology, revisited

We strolled the San Francisco wharf, stopping at the National Historic Park Maritime Museum and checking out the ships on the Hyde Street Pier.

En route to the Marina Green, at Fort Mason, we discovered a fabulous bookstore (used and new materials, sales benefit SF libraries).

Not far from the bookstore, near Aquatic Park, we approached this refreshingly pungent tree.

Click the image; it will grow.


According to the Common Core State Standards, children in kindergarten and first grade must learn how common inflectional suffixes like -s, -ed, -ing, -er and -est create various forms of the same word, as with grow, grows, growing, and big, bigger, biggest.

But inflections are only the beginning. The inflectional suffix -er in greener and brighter is not the same as the derivational suffix -er in painter and preacher. (See The Slippery Suffix -er.)

By third grade, students need to be working with derived words, particularly those countless English words formed by adding a derivational suffix. (Read about suffixes.)


Finding a semantic overlap  between tree and treelet is a matter of morphological problem solving (Anglin, 1993). This involves knowledge of prefixes and suffixes, and a readiness to seek similarities in form and meaning across words. It also involves analogy: "I know what  a piglet is, so I can guess what a treelet is." The ability to problem solve via analogies or morphemes is facilitated by knowledge of similar words: booklet, owlet, piglet, eaglet, and applet, a small computer application.

Eventually, if students are shown how to explore morphological connections and taught common prefixes and suffixes, they become more apt to seek that satisfying "ah-ha" moment, when word meanings click into place. It's often quite rewarding, like the snap of a puzzle piece. This moment is more likely to happen when students are reading, rather than listening.

Along our walk we visited this fabulous -- and free -- museum. Of course, I began to wonder about these two words, given their close proximity on the display. My first thought was that the root brig might mean "ship"...

...but in addition to brig and brigantine, we have brigadier and brigade. Are they all part of the same family of words? (So then I thought the root meant either "ship" or 'to fight').

Asking the question is important. Coming up with an answer is secondary to asking the question. Are students asking the question? Are teachers modeling this habit of thought?


In kindergarten, analyze words like big, bigger, and biggest (inflections).
Also analyze tip, tipping, and tipped (inflections).

By first grade, birdhouse, doghouse, and -- not quite the same pattern -- tree house (These are compound words, but notice a tree does not live in a tree house, unlike the birdhouse and doghouse examples. Also, a tree house is an open compound, rather than closed.)

Within a year or two, pig-piglet, owl-owlet, and tree-treelet (derivations).

Into middle school and beyond, address more complex derivations: brig, brigantine, brigand, brigadier, brigandage, etc. The word brig is perhaps a clip, a shortened form of brigantine. However, brig has developed a unique meaning over the years. By the way, according to Online Etymology Dictionary, the root does mean "to fight" (Middle English via Italian).

According to seminal research by Jeremy Anglin (1993), inferring word meaning via morphological reasoning predicts vocabulary growth. Anglin tested children in grades 1, 3, and 5, finding a sharp increase in word knowledge between grades 3 and 5. He suggested that this steep increase is largely due to increased awareness of the process of suffixation, in particular, the process of creating new words by adding derivational suffixes. Those students who were more skilled in this type of "morphological problem solving" performed comparatively better on the vocabulary test.

While root words (words that have no prefix or suffix attached, like shoe, rope, tree) accounted for the most words known by the average first grade student, derived words accounted for the most words known by a typical fifth grader.

The chart is from Anglin's monograph. His test included treelet, among other words. I added some color and the other forms of tree as examples only, providing an instance of each of the five types of words he included in the test: root words, inflected words, derived words, literal compounds, idioms.

In the years since Anglin's monograph, the relationship between linguistic insight and literacy has become a fairly hot topic in research circles. Not surprisingly, Berninger et al. (2010) found a similar linear relationship between vocabulary knowledge and morphological insight, in large part confirming Anglin's findings.

Promising research by Bauman et al. (2007) suggests that vocabulary increases as a result of a combined instructional focus that includes four components: 1) creating a language-rich learning environment, 2) providing explicit word instruction, 3) teaching word-learning strategies (including inferring meaning via morphological problem solving), and 4) fostering word consciousness. This line of inquiry is based on theories advanced by Graves (2006).  See the MCVIP post, where a large team of researchers describe even newer findings.

The more our vocabulary grows, the more we are able to make connections when practicing The Mindful Zen of Morphology. The more we make connections, the more our vocabulary grows.
