The wpart element

On this page:

The wpart element represents a segment of a word.

The wpart element is typically used to distinguish the parts of a word (root, stem and affix), compound word, portmanteau or homograph. It can also be used in grammatical contexts to identify morphemes, graphemes and other divisions and boundaries within a word.

The wpart element additionally can be used in place of soft hyphens to identify line ending break locations, if external formatting options are limited.

The role attribute optionally expresses the semantic nature of the word part. No implicit value is associated with the wpart element.

Usage Example

those <w><wpart role="root">near</wpart><wpart role="stem">est</wpart></w> to the axis
