╭───────────┬────────────┬────────────╮ │ Neuter │ Masculine │ Feminine │ │ ───────── │ ────────── │ ────────── │ │ Esto │ este estos │ esta estas │ This, these │ Eso │ ese esos │ esa esas │ That, those │ Aquello │ aquel │ aquella │ (far-away thing │ │ -aquellos │ -aquellas │ or things) ╰───────────┴────────────┴────────────╯
Note: the masculine form changes from -e- to -o- in plural form! ESE -> ESOS
ChatGPT swears that neuter forms ESTO and ESO cannot be pluralized, although you have to use ESTOS and ESOS (as masculine forms, although why not just say that neuter and masculine plural forms are identical instead?)
