• Dictionary form: ٱلْـَٔاخِرَة, the feminine of آخِر, "last" (corpus lemma آخِر, 155 times in the Quran), as in «وَبِٱلْـَٔاخِرَةِ هُمْ يُوقِنُونَ» (2:4).
• Pattern: فَاعِلَة (fāʿila), the feminine of فَاعِل. It stands for الدار الآخرة, "the last abode", as in 29:64 below; its pair is الدنيا, "this world".

Ibn Faris, Maqāyīs al-Lugha, root أخر, vol 1, p 69

الهمزة والخاء والراء أصل واحد إليه ترجع فروعه، وهو خلاف التقدم

One origin to which its branches go back: the opposite of coming first. (So ākhir is what comes last.)

وَمَا هَٰذِهِ ٱلْحَيَوٰةُ ٱلدُّنْيَآ إِلَّا لَهْوٌ وَلَعِبٌ وَإِنَّ ٱلدَّارَ ٱلْـَٔاخِرَةَ لَهِىَ ٱلْحَيَوَانُ لَوْ كَانُوا۟ يَعْلَمُونَ

And this worldly life is not but diversion and amusement. And indeed, the home of the Hereafter - that is the [eternal] life, if only they knew.

Surah Al-Ankaboot (29), ayah 64 · Saheeh International

Why this ayah: «وَإِنَّ ٱلدَّارَ ٱلْـَٔاخِرَةَ لَهِىَ ٱلْحَيَوَانُ», "the home of the Hereafter: that is the [eternal] life": the full phrase behind the word, and the thought of V1 p8 ¶1a: people are asleep, and wake when they die.
