Correct spelling for the English word "Analemma" is [ˈane͡ɪlmə], [ˈaneɪlmə], [ˈa_n_eɪ_l_m_ə] (IPA phonetic alphabet).
Analemma is a term in astronomy and geography that refers to a figure-eight-shaped curve traced by the position of the Sun in the sky over the course of a year, as observed at the same time each day from a fixed location on Earth. The analemma curve arises due to the combination of the Earth's axial tilt and its elliptical orbit around the Sun.
The curve is formed by plotting the Sun's declination (angular distance from the celestial equator) against the equation of time (the difference between solar time and mean solar time) on a graph. The shape of the analemma is determined by various astronomical phenomena, including the tilt of the Earth's rotational axis (which causes the Sun's position to vary over the year) and the Earth's elliptical orbit (which affects the time taken for the Earth to orbit the Sun).
The analemma allows astronomers and navigators to determine the exact position of the Sun at any given time of the year. It is often used to create sundials that accurately account for the variation in solar time throughout the year. Additionally, the analemma has significance in geodesy, as it provides important information for calibrating cameras and satellite imagery, as well as estimating the Earth's axial tilt and orbital parameters.
Overall, the analemma is a fascinating astronomical phenomenon that illustrates the Earth's complex relationship with the Sun and provides important insights for various scientific disciplines.

The word "analemma" comes from the Greek word "análema" (ἀνάλημμα), which means "support" or "prop". This term is derived from the Greek verb "analeín" (ἀναλεῖν), which means "to raise" or "to lift up".
The term "analemma" initially referred to a support or prop used to hold up a sundial. However, in modern usage, it primarily refers to the figure-eight-shaped diagram that represents the apparent path of the Sun in the sky when observed at the same time each day for a year. This figure-eight shape is created due to the tilt of the Earth's axis and its elliptical orbit around the Sun.
