Additional search function by suffix

A suffix is an affix added to the end of a word or stem, serving to form a new word or functioning as an inflectional ending, such as -ness in gentleness, -ing in walking, or -s in sits. It is very important for learners to understand suffixes when they learn English words because a suffix is one of the stems. The understanding of many stems can help learners to learn many English words because many words are comprised of some aggregations of stems. The search function by suffixes enables the search of English words from a suffix, and it lists English words with the same suffix. Learners of English can learn some English words simultaneously because some English words have the same suffix.
