The suffix -ene is used in organic chemistry to form names of organic compounds where the -C=C- group has been attributed the highest priority according to the rules of organic nomenclature. Sometimes a number between hyphens is inserted before it to say that the double bond is between that atom and the atom with the next number up. This suffix is taken from the end of the word ethylene, which is the simplest alkene. The final "-e" disappears if it is followed by a suffix that starts with a vowel, e.g. "-enal" which is a compound that contains both a -C=C- bond and an aldehyde functional group. If the other suffix starts with a consonant or "y", the final "-e" remains, e.g. "-enediyne" (which has the "-ene" suffix and also the "-yne" suffix, for a compound with a double bond and two triple bonds.)

The Ene River (Spanish: Río Ene) is a Peruvian river on the eastern slopes of the South American Andes.

The points of the compass are points on a compass, specifically on the compass rose, marking divisions of the four cardinal directions: North, South, East, West. The number of points may be only the 4 cardinal points, or the 8 principal points adding the intercardinal (or ordinal) directions northeast (NE), southeast (SE), southwest (SW), and northwest (NW). In meteorological usage further intermediate points are added to give the sixteen points of a wind compass. Finally, at the most complete in European tradition, are found the full thirty-two points of the mariner's compass. In ancient China 24 points of the compass were used.

Ñ (lower case ñ, International Phonetic Alphabet: "énye") is a letter of the modern Latin alphabet, formed by placing a diacritical tilde on top of an N. It became part of the Spanish in the eighteenth century, when it was first formally defined. Subsequently it has been used in other alphabets, especially those influenced by the Spanish one: Galician, Asturian, Basque, old Aragonese (Grafía de Uesca de 1987), Chavacano, Filipino, Chamorro, Guarani, Quechua, Mapudungun, Mandinka, and Tetum alphabets, as well as in Latin transliteration of Tocharian and Sanskrit, where it represents . It represents in Crimean Tatar. In Breton and in Rohingya, it denotes nasalization of the preceding vowel.
