The correct spelling of the phrase "is running" is /ɪz/ /ˈrʌnɪŋ/. The sound "is" is spelled with the letter "s" and the sound "run" is spelled with "r" and "u".

This phrase is used to describe a present continuous action that someone or something is currently doing.
"Is running" is a verb phrase that consists of the verb "is" (the present tense form of the verb "be") and the participle "running" (the present participle form of the verb "run"). This phrase is commonly used to describe the action of someone or something engaging in the act of running.
The term "running" itself refers to the act of moving swiftly and rapidly on foot, usually involving a combination of a bouncing gait and a series of strides, where both feet are off the ground at certain moments. Running is a fundamental form of human locomotion and is often considered a sport, exercise, or a means of transportation. It typically involves the coordinated movement of various muscles, especially those in the legs, to propel the body forward.
In the context of "is running," the auxiliary verb "is" indicates the present tense and corresponds to the third-person singular, suggesting that the subject (a person, an animal, or an object) is currently engaged in the action of running. For example, in the sentence "The dog is running," the phrase indicates that the dog is currently in motion, using its legs for rapid movement. The present participle "running" emphasizes the ongoing nature of the action, suggesting that the subject is actively involved in running at the time of reference.
The word "running" is derived from the Old English word "rinnan" which means "run, flow, or move swiftly". It is related to the Middle Dutch word "runnen" and the Old High German word "rinnan", both of which have similar meanings. Ultimately, the origins of this word can be traced back to the Proto-Germanic word "*rinnaną".
