Explicación:
Me imagino que estás viendo this / these, that / those y obviamente el plural de las palabras.
• These significa "estas" y es el plural de this (este)
• Those significa "esos" es el plural de that (eso)
Recuerda que:
→ That y those se usan para hablar de cosas que están lejos de algo o alguien
→ This y these se utilizan para decir cosas que están cerca
El plural de los sustantivos se forma agregando "s" mayormente. Si el sustantivo termina en consonante +y se elimina la -y y se agrega "ies" (baby / babies). En el ingles todo se divide en regular e irregular, pues está no es la excepción y también hay sustantivos regulares e irregulares.
→ Man - men (hombre / hombres)
→ Woman - women (mujer / mujeres)
→ Sheep - sheep (oveja / ovejas)
→ Thooth - theeth (diente / dientes)
