Like other European languages, academic English makes use of Latin abbreviations and expressions. You must have also met some of them while reading Russian academic texts, where such expressions are easy to notice, because they are often written in the Roman alphabet. In English texts, such expressions (rather than abbreviations) are sometimes given in italics.
