| Mar 14, 2021 at 18:07 | comment | added | R.P. | X-oid < X-oeidēs was already used in Ancient Greek as a suffix meaning 'looking like X', from eido 'to see'. etymonline.com/word/-oid | |

| Mar 13, 2021 at 5:49 | comment | added | marshal craft | My guess would be Rutherford in his universal algebra, the precursor to model theory. Were an algebra is a set with binary operation and various logical properties of some formal logic etc, specific these logical properties are, I think they abstract groups basically. I would imagine if Rutherford didn't use the word monoid, he probably started the notions which would lead to it and it's eventual naming. | |

| Mar 12, 2021 at 22:37 | comment | added | Donu Arapura | Perhaps this is more appropriate for Mathoid Overflow. It's not really a math question... | |
| Mar 12, 2021 at 22:20 | comment | added | YCor | At the first place the suffix -oid is not mathematical (dictionnaire.exionnaire.com/que-signifie.php?mot=-oide). My favorite mathematical one anyway, in French, is patatoïde, one of the most important geometric shapes in the whole history. | |
| Mar 12, 2021 at 21:22 | comment | added | Gerald Edgar | spheroid 1664 Barrow. From Latin sphaeroīdēs, from Greek σϕαιροειδής The Oxford English Dictionary says the -oid suffix is used primarily in mathematics and in zoology. | |

| Mar 12, 2021 at 20:55 | comment | added | Benjamin Steinberg | Of course the horizontal categorification of monoid is category and not monoidoid :) | |
| Mar 12, 2021 at 20:54 | comment | added | Simon Henry | The only consistent use of the -oid suffix I know is for Horizontal categorication (ncatlab.org/nlab/show/horizontal+categorification), so typically, groupoid, algebroid, ringoid, etc... in which case the origin is definitely the name "groupoid". But it is unclear if all the examples you mention fit into this picture ? Otherwise the use of -oid to name "something vaguely ressembling something else" does not strike me as really being a fashion nor being specific to mathematics. | |
| Mar 12, 2021 at 20:52 | comment | added | Benjamin Steinberg | Brandt Introduced groupoids in 1926 but he wrote in German and maybe used some Germanic equivalent suffix rather than oid. | |
