Pitch accent of nominalizers

Question

Do the nominalizers "no" and "koto" have recessive accent (i.e. no downstep) or downstep after the first syllable? Or are they enclitic (i.e. unaccented unless following a word with no downstep in which case they accent the final syllable, like だ)?

Answer 1

• の (not same pattern with the postposition の!)

  • after accentless verbs and na-adjectives: downstep before the particle

    なる{LH} "make sound" → なるの{LHL}

    かえる{LHH} "change (t.)" → かえるの{LHHL}

    みつめる{LHHH} "stare at" → みつめるの{LHHHL}

    せいかくだ{LHHHH} "accurate" → せいかくなの{LHHHHL}

  • after accented verbs and na-adjectives: keeps the pitch

    なる{HL} "become" → なるの{HLL}

    かえる{HLL} "go home" → かえるの{HLLL}

    につめる{LHHL} "boil down (t.)" → につめるの{LHHLL}

    ふせいかくだ{LHLLLL} "inaccurate" → ふせいかくなの{LHLLLLL}

  • after i-adjectives: always downstep before い

    あつい{LHH} "thick" → あついの{LHLL}

    あつい{LHL} "hot" → あついの{LHLL}

• こと

  • after accentless words: takes over the accent (final syllable)

    なる{LH} → なること{LHHH} → なることが{LHHHL}

    かえる{LHH} → かえること{LHHHH} → かえることが{LHHHHL}

    みつめる{LHHH} → みつめること{LHHHHH} → みつめることが{LHHHHHL}

    あつい{LHH} → あついこと{LHHHH} → あついことが{LHHHHL}

    せいかくだ{LHHHH} → せいかくなこと{LHHHHHH} → せいかくなことが{LHHHHHHL}

  • after accented words: keeps the pitch

    なる{HL} → なること{HLLL}

    かえる{HLL} → かえること{HLLLL}

    につめる{LHHL} → につめること{LHHLLL}

    あつい{LHL} → あついこと{LHLLL}

    ふせいかくだ{LHLLLL} → ふせいかくなこと{LHLLLLLL}

A verb or adjective whose last syllable is high is always accentless. The list of word accents is available from, for example, here.
