Hendiadys ( / h ɛ n ˈ d aɪ . ə d ɪ s / ) is a type of speech used to highlight an idea. It works by replacing a relationship between two ideas with a simple word like "and." Instead of one idea affecting another, two separate ideas are joined together using "and."

In English, this is sometimes called "two for one" or "figure of twins." The term comes from Greek: "hen dia duoin," which means "one through two." In English, other forms like "hendiaduo" and "hendiaduous" have been used rarely. The 17th-century Bible commentator Matthew Poole used "hendiaduous" in his writings about parts of the Bible, including Genesis 3:16, Proverbs 1:6, and Isaiah 19:20.

Use and effect

A hendiadys changes a noun and an adjective into two nouns connected by a word like "and." For example, "sound and fury" from Shakespeare's Macbeth creates a stronger image than "furious sound." In this case, the idea that was originally described by the adjective becomes its own separate noun.

Another example is "Dieu et mon droit," found on the coat of arms of the United Kingdom. Hendiadys works best in English when the adjective and noun forms of a word are the same. For example, "the cold wind went down the hall" can become "the cold and the wind went down the hall." Similarly, "he came despite rain and weather" replaces "he came despite the rainy weather."

Two verbs can also be joined in this way, such as "come and get it" (or "come get it" in American English). Fowler, a writer on language, says "try and…" is a true example of hendiadys, as it replaces "try to…" The origin of "try and…" is explained in the "Usage Note" section of the Merriam-Webster Dictionary.

The word "and" can sometimes be left out, as in "This coffee is nice and hot," which can become "This is nice hot coffee." In both cases, the coffee is described as hot to a nice degree, not as a separate idea.

When hendiadys does not work well, it may seem repetitive. For example, the Latin phrase "cum amicitia atque pace," meaning "with friendship and peace," originally used hendiadys for emphasis. However, it is often translated as "with peaceful friendship," which removes the hendiadys structure and weakens the original emphasis.

In classical and Biblical literature

Hendiadys is a figure of speech used in Latin poetry. It appears in Virgil's Aeneid, such as in Book 1, line 54: vinclis et carcere, which literally means "with chains and prison," but actually refers to "with prison chains."

In the Hebrew Bible, Exodus 15:4 includes the phrase מַרְכְּבֹת פַּרְעֹה וְחֵילוֹ, literally translated as "chariots of Pharaoh and his army," but it means "the chariots of Pharaoh's army."

Leviticus 25:47 uses the Hebrew phrase גֵּר וְתוֹשָׁב, which literally means "alien and resident," but the phrase refers to a "resident alien."

In Lamentations 2:9, the Hebrew phrase אִבַּד וְשִׁבַּר literally translates to "ruined and broken," but it means "destroyed completely" or "smashed to bits."

Isaiah 4:5 includes the phrase translated as "cloud by day and smoke," which sometimes is interpreted as a hendiadys meaning "a cloud of smoke by day."

In Mark 11:24, the Koine Greek phrase ὅσα προσεύχεσθε καὶ αἰτεῖσθε literally means "whatever you pray and ask," but it refers to "whatever you ask in prayer."

William Shakespeare uses hendiadys in many of his works, especially in Hamlet. For example, Laertes uses this figure of speech repeatedly when warning Ophelia, such as "safety and health" (1.3.20), "voice and yielding" (1.3.22), and "morn and liquid dew" (1.3.41). One of the most well-known examples is Hamlet's line, "Oh what a rogue and peasant slave am I" (2.2.538).

As linguistic terminology in describing Turkic languages

Hendiadys is the term used in Turkic linguistics to describe certain types of word combinations. According to Johanson, when two words with similar meanings are joined directly in a compound, this is called hendiadys.

The asyndetic type, which combines two nouns without a connector, is used in coordinative compounds. These are sometimes called twin words or binomes. In these cases, two nouns with similar meanings form a compound known as hendiadys, or they may form a hyponym compound to express a broader concept.
