You are technically correct! Alphabets (ABC) are for phonemes, syllabaries are for syllables (hiragana, Cherokee), logograms are for words (chinese characters). Of course, some writing systems are very much hybrids (like Chinese, or hieroglyphics, or even the humble ampersand).

To be sure, 'logogram' is an even worse word than 'ideograph' for what the Chinese writing system is.
