Word square place names). However, 11-squares are possible if words from a number of languages are allowed ("Word Ways", August 2004 and May 2005). It is possible to estimate the degree of difficulty of constructing word squares. 5-squares can be constructed with as little as a 250-word vocabulary. Roughly, for each step upwards, one needs four times the number of words. For a 9-square, one needs over 60,000 9-letter words, which is practically all of those in single very large dictionaries. For large squares, the vocabulary prevents selecting more "desirable" words (i.e. words that are unhyphenated, in common use, without contrived inflections,
Learning to read vowel-pairs that help to make up words that go beyond the basic level.The faster a child can see that the word "together" is "to-ge-ther", the faster the reader will become a more fluent reader. As children move forward with their reading skills, they learn a great deal about what is really inside a word; the stem, roots, prefixes and suffixes that make up morphemes of the language. By this stage, children already know about the common bound morphemes such as "s" and "ed" because these are attached to many words. Decoding readers become exposed to many types of morphemes such
