Pronunciation: [ɹˈatlə] (IPA) 
The word "rattler" is spelled with two syllables and has the IPA phonetic transcription of /ˈræt.lər/. The first syllable, "rat," is spelled with the letter 'r' followed by the vowel 'a.' The second syllable, "tler," is spelled with the letters 't' and 'l' pronounced together, followed by the vowel 'e' and the letter 'r.' This spelling reflects the sound of the word, which is a type of snake that makes a rattling sound with its tail.
A "rattler" is a noun that refers to a type of venomous snake belonging to the rattlesnake family, specifically the genera Crotalus and Sistrurus. Rattlers are known for their distinctive "rattle" located at the end of their tails, which produces a distinct sound when shaken as a warning signal. This specialized structure is made up of hollow, modified scales that resonate with each other, emitting a buzzing noise. It serves as a defensive mechanism to warn potential threats and predators of their presence, allowing other animals to choose to back off or engage with caution.
Rattlers are typically found in North and South America, inhabiting a wide range of habitats from deserts to forests. They are characterized by their triangular-shaped heads, thick and muscular bodies covered in scales, and distinctive patterns of spots, bands, or diamonds along their bodies. With their keen sense of smell and heat-sensing pits on their faces, rattlers are skilled hunters. These snakes primarily feed on small animals like rodents, birds, lizards, and even other snakes.
Rattlers have a potent venom that they deliver through fangs located in the front of their mouth. When threatened or attacking prey, they strike with great speed, injecting venom that immobilizes or kills their target. The venom is a complex mixture of enzymes, toxins, and proteins that causes tissue damage, organ failure, and in severe cases, can be lethal to humans if left untreated. Thus, encountering a rattler in the wild should be approached with caution and avoided if possible, as their venomous bite poses a serious health risk.

The word "rattler" has a couple of different etymological origins, depending on the specific context. Here are two possible explanations:
1. Rattler (Snake): The term "rattler" is commonly used as a colloquial term for a rattlesnake. It is derived from the verb "rattle" and refers to the snake's distinctive warning sound produced by its tail. The verb "rattle" itself comes from the Middle English word "ratelen", which originated from the Old English word "hrǣtlian". The root of this word is likely onomatopoeic in nature, imitating the sound produced by the snake's tail.
2. Rattler (Train): In the context of trains, particularly in North America, "rattler" is a nickname or shortened form of "rattling car".
