penicillus การใช้

• Crayon ultimately derives from the Latin for chalk, so it is rather the French who have the word wrong, using it to mean a constructed drawing implement with the nib encased ( like a paintbrush or the Latin penicillus ) rather than a simple stick of drawing medium as the English uses of crayon and chalk.
• He gives this example : The drug name " penicillin " was coined by Alexander Fleming from the Latin for " paintbrush ", which is " penicillus " . " Methicillin ", a type of penicillin, gained its name by attaching the stem "-cillin " ( from the United States Adopted Names Council's list of stems ) to a prefix " meth " which has no inherent meaning.
