thoro-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly. Some degree of stress is always maintained on the first syllable. If the subsequent element is an existing word, it is likely to retain its original stress pattern, e.g. thorogummite n. Brit.

/ˌθɔːrə(ʊ)ˈɡʌmʌɪt/, U.S.

/ˌθɔrəˈɡəˌmaɪt/,

/ˌθoʊrəˈɡəˌmaɪt/.

Origin: Formed within English, by compounding. Etymons: thorium n., -o- connective.

Etymology: < thor- (in thorium n.) + -o- connective.

In names of compound salts, minerals, etc. e.g. thoroˈgummite n. [ < thoro- comb. form + gummite n.; compare quot. 1889¹] Mineralogy a hydrated thorosilicate of uranium. thoroˈsilicate n. Chemistry a silicate in which part of the silicon is replaced by thorium.

1889 Amer. Jrnl. Sci. & Art 38 481 We name this mineral thoro-gummite, because it is a gummite in which the water has been replaced by the thorite molecule.

1889 Amer. Jrnl. Sci. & Art 38 480 It seems better to regard the mineral as a hydrated thoro-silicate of uranium, rather than as a urano-silicate of thorium.

1909 Cent. Dict. Suppl. Thorogummite..like other native compounds of thorium and uranium, has marked radio-active properties.
