kedelapan

Kedelapan is an Indonesian and Malay ordinal numeral meaning the eighth in a sequence. It is formed from the cardinal number delapan (eight) with the prefix ke- and the suffix -an, producing a determiner or modifier that marks position.

In usage, kedelapan functions like other ordinals: it typically precedes a noun to specify order, for example kedelapan buku (the eighth book), kedelapan bulan (the eighth month), or kedelapan posisi (the eighth position). It can also stand as a nominal reference to the item in that position, such as “kerja kedelapan” in some contexts, though more common is its attributive use before a noun.

Kedelapan contrasts with the cardinal delapan, which simply means the number eight. The form kedelapan emphasizes order rather than quantity and is part of a broader Indonesian and Malay pattern that forms ordinals with ke- and -an. In dates or sequences, kedelapan is used to indicate the position within a series, rather than the amount alone.

Etymology traces kedelapan to the root delapan, enhanced by the derivational affixes ke- and -an to express ordinal meaning. This construction is widely understood in formal and informal Indonesian, as well as in Malay, reflecting shared numeral morphology across both languages.
