Pronunciation: [ˈiːt͡ʃ θˈɪŋz] (IPA) 
The spelling of the phrase "each things" is incorrect in English. The correct way to say it is "each thing" with [itʃ] and [θɪŋ] sound, respectively. The IPA phonetic transcription for "each thing" is /itʃ θɪŋ/. It is common for non-native speakers to make this error due to the similarity of the sound /s/ and /θ/. Remember, in English, the word "thing" never takes an 's' in its singular form.
The phrase "each things" does not have a specific etymology, as it seems to be a combination of the words "each" and "things".
The word "each" comes from the Old English word "ǣlc" meaning "every, each, any". It can be traced back to the Proto-Germanic word "ailīkoz" and ultimately to the Proto-Indo-European root "*h₂ey-li-" meaning "of the group".
The word "things" comes from the Old English word "þing" which originally meant "assembly" or "meeting". It can be traced back to the Proto-Germanic word "*þingą" and is related to the Old Norse word "þing", the German word "Ding", and the Dutch word "ding".
