| Semisulcospina | A genus of operculate snails (family Pleuroceriidae, subclass Prosobranchiata). An oriental form, Semisulcospina libertina, is the first intermediate host of a number of trematodes, including Paragonimus westermani. Origin: semi-+ L. Sulcus, a furrow + spina, thorn, spine (05 Mar 2000) |

| semisystematic name | A name of a chemical of which at least one part is systematic and at least one part is not (i.e., is trivial). For example, calciferol includes the -ol suffix denoting an -OH radical, while calcifer-, which has no systematic meaning, is used only in this word. Cortisone contains the -one suffix, indicating a ketone group, but the rest of the term derives from cortex (adrenal). Hippuric acid (trivial) may be defined as N-benzoylglycine (semitrivial name); benzoyl is systematic for the C6H5-CO-radical, whereas glycine is the trivial name for alpha-aminoacetic (or 2-aminoethanoic, to be completely systematic) acid, and the N signifies that the benzoyl is attached to the nitrogen of glycine; from this, the structure C6H5-CO-NH-CH2-COOH is uniquely defined. Many generic or nonproprietary names of drugs, including USAN names, hormones, etc., are semitrivial in this chemical sense, although often termed trivial names; distinction between trivial and semitrivial is not often made. Synonym: semitrivial name. (05 Mar 2000) |

| semantics |
In linguistics, the study of meanings. In computer science, the term is frequently used to differentiate the meaning of an instruction from its format. The format, which covers the spelling of language components and the rules controlling how components are combined, is called the language's syntax. For example, if you misspell a command, it is a syntax error. If, on the other hand, you enter a legal command that does not make any sense in the current context, it is a semantic error.
