A smiley, sometimes referred to as a smiley face, is a basic ideogram that represents a smiling face. Since the 1950s it has become part of popular culture worldwide, used either as a standalone ideogram, or as a form of communication, such as emoticons. The smiley began as two dots and a line to represent eyes and a mouth. More elaborate designs in the 1950s emerged, with noses, eyebrows, and outlines. A yellow and black design was used by New York-based radio station WMCA for its "Good Guys" campaign in the early 1960s.
In music, sharp, dièse (from French), or diesis (from Greek) means, "higher in pitch". More specifically, in musical notation, sharp means "higher in pitch by one semitone (half step)". A sharp is the opposite of a flat, a lowering of pitch. The ♯ symbol itself is conjectured to be a condensed form of German ligature sch (for scharf) or the symbol ƀ (for "cancelled flat"). In intonation, sharp can also mean "slightly higher in pitch" (by some unspecified amount).
An emoticon (əˈmoʊtəkɒn, , rarely ɪˈmɒtɪkɒn, ), short for "emotion icon", is a pictorial representation of a facial expression using characters—usually punctuation marks, numbers, and letters—to express a person's feelings, mood, or reaction, without needing to describe it in detail. The first ASCII emoticons are generally credited to computer scientist Scott Fahlman, who proposed what came to be known as "smileys" - :-) and :-( - in a message on the bulletin board system (BBS) of Carnegie Mellon University in 1982.
The hammer and sickle (Unicode: ☭) is a symbol meant to represent proletarian solidarity, a union between agricultural and industrial workers. It was first adopted during the Russian Revolution at the end of World War I, the hammer representing workers and the sickle representing the peasants. After World War I (from which the Russian Empire withdrew in 1917) and the Russian Civil War, the hammer and sickle became more widely used as a symbol for labor within the Soviet Union and for international proletarian unity.
An emoji (ᵻˈmoʊdʒi: ; plural emoji or emojis; 絵文字) is a pictogram, logogram, ideogram, or smiley embedded in text and used in electronic messages and web pages. The primary function of emoji is to fill in emotional cues otherwise missing from typed conversation. Emoji exist in various genres, including facial expressions, common objects, places and types of weather, and animals.
