Pronunciation: [flˈɪtəɹɪŋ] (IPA) 
The word "flittering" is spelled with double "t" because it reflects the pronunciation of the word. Using the IPA phonetic transcription, the word can be transcribed as /ˈflɪtərɪŋ/. The double "t" represents a gemination or a long consonant sound in English, which is characterized by a brief pause before the consonant is pronounced. This is why "flittering" has two "t's" in the spelling to indicate the sound of the word.
Flittering is an adjective that describes the action or behavior of moving quickly and lightly from one place to another, usually in a somewhat erratic or fluttering manner. The term is often associated with small, agile creatures such as birds, butterflies, or insects that fly or move rapidly and with a certain degree of unpredictability.
In a literal sense, flittering refers to the rapid and intermittent movement of wings or limbs while in flight, resulting in a series of quick, small, and often indistinct motions. These movements can give the impression of fleeting or flickering, as if the object or creature appears for a brief moment before disappearing again.
Figuratively, flittering is also used to describe human behavior characterized by restlessness, constant motion, or a lack of focus. It may refer to someone easily distracted or switching between different tasks, ideas, or interests without settling on any one of them for an extended period. The term can imply a sense of fickle or superficial engagement with various activities or subjects, lacking depth or commitment.
Overall, flittering suggests a sense of movement that is elusive, unsteady, or transitory, whether in the physical world or in human actions and behavior.
The word "flittering" is derived from the Middle English word "fleteren", which was in turn derived from the Old English word "floterian". "Fleteren" originally meant to flutter or fly about, and "floterian" meant to float or fly fleetingly. These words ultimately stem from the Proto-Germanic root "flutōną", meaning to float or swim. Over time, the meaning of "flittering" has evolved to refer to moving quickly and lightly, often with a fluttering or flickering motion.
