「〜の」⇨ 平板型

Explanation 説明

There are several words that lose their accent when connected to の. This change occurs in two places:

  1. for 尾高型 words L〜H(L)
  2. for a limited number of words that either have the syllabic nasal or diphthongs at the end and are accented on the final syllable〈にほ\、きの\う、おとと\い

However this pattern does not apply to words relating to numerals, counters, order, etc… Another time this pattern may not occur is when under the influence of a silenced vowel. Also some words may occur as either their original form or new form. Since the original form has a fall early in the phrase, the original form is used more when adding emphasis.

Silenced vowels(母音の無声化)occur for rows い段 and う段 intersecting with columns
か行、さ行、た行、は行、ぱ行, but only when they come before those columns. Simply put,
if the vowel that comes between any combination of k・s・t・h・p, is 'i' or 'u'
it will automatically become a whispered (voiceless, silenced, etc..) sound. Ex:
くち k(u)chi、ちから ch(i)kara、つき ts(u)ki、すきやき s(u)kiyaki、だれひとり dareh(i)tori
