<div class='writeup-body'>In 関西弁（かんさいべん）, the <span class='info-highlight' data-term='連用形・れんようけい'>conjunctive form</span> of adjectives that interacts with ない can be altered slightly. This alteration results in く being dropped, and ない being connected directly to the adjective stem. This form of negative adjectives may be used with any structure that would usually have the く alteration when being conjugated (except ない itself).<br>ない continues to have the same role as it does in standard Japanese, stating that something is 'not (A)'.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>なんか<span class='vocab-popout' data-vocab-id='309'>今日（きょう）</span><span class='gp-popout vocab-popout' data-gp-id='968' data-vocab-id='519'>寒（さむ）ない</span>？</div><div class='writeup-example--english'>Don't you think it's kind of cold today?</div></li><li class='writeup-example'><div class='writeup-example--japanese'><span class='gp-popout' data-gp-id='30'>この</span><span class='vocab-popout' data-vocab-id='501'>子（こ）</span><span class='gp-popout vocab-popout' data-gp-id='968' data-vocab-id='379'>凄（すご）ない</span>？五歳（ごさい）<span class='gp-popout' data-gp-id='130'>なのに</span><span class='vocab-popout' data-vocab-id='849'>私（わたし）</span><span class='gp-popout' data-gp-id='108'>より</span><span class='vocab-popout' data-vocab-id='985'>踊（おど）る</span><span class='gp-popout' data-gp-id='77'>のがうまい</span>。</div><div class='writeup-example--english'>Isn't this kid impressive?
