Usage and meaning of the word analog in Russian and English

АНА́ЛОГ — явление, соответствующее другому явлению, в отличие от копии не полностью, а по каким-либо отдельным свойствам. While the English word “analog” can have this same meaning, most Americans do not use it to explain that something is analogous to something else.  This is why I urge you to use synonyms instead – “equivalent”, “analogous”, “interchangeable” or “undifferentiated” (depending on the context of course).
