For example, hyperbolic is a word for a something related to hyperbole. There is a word that's an adjective or a noun for these type of words and I cannot find one for this one. Also, parabola > parabolic. I was thinking of aphosis but that is not a word, I think.

    I'm voting to close this question as off-topic because it is word golf. If you need a word to help you express a specific meaning, we can help, but I don't think this sort of word puzzle is useful to EFL learners. If the question can be edited to make it clearer how this relates to learning practical English, I will retract my close vote. This may be on-topic at English Language & Usage. – ColleenV Jun 11 '16 at 16:54
  • This question has been moved to here from that website. Should I repost it there? – Fred Caston Jun 12 '16 at 14:09
  • If it was moved, closing it here would have rejected the migration and sent it back. Was there a reason given why it was closed on English Language & Usage? Reposting isn't the right way to go about it - editing the question to address the reasons why it was closed is. – ColleenV Jun 12 '16 at 16:16

The word itself is derived from Greek: a means 'no' and photos means 'light'. That more or less fits with its meaning:

being the deep zone of an ocean or lake receiving too little light to permit photosynthesis

Not all adjectives in English have a corresponding noun which is in common use.

  • You've failed to answer the question. The answer would be words that have been derived from aphotic or have derived from aphotic. If only aphoticity or aphoticness were words; It may have been easier. I'm aware of what you're saying and I'm aware of the definition. – Fred Caston Jun 11 '16 at 13:21

    @FredCaston I think he does answer it - there is no noun derivative or parent. While I agree that a parabola is parabolic, that does mean that all adjectives have a direct noun equivalent. In the case of aphotic, I think the closest you'll find is the compound aphotic-zone – PerryW Jun 11 '16 at 13:33
  • Perhaps, it is. – Fred Caston Jun 11 '16 at 14:36
