willing, willingly, of one’s own free will pertaining to being willing to do something without being forced or pressured In a number of languages ‘willingness’ to perform some action is expressed negatively, for example, ‘not having to’ or ‘not being forced to’ or ‘not being told one must.’ A positive expression of ‘willingness’ may be indicated idiomatically by a phrase such as ‘my heart approves.’
