You would use "Usted" or "Ud."
It depends on who you are talking to. Spanish verbs are conjugated differently when the subject is considered either formal or informal to the speaker."Necesitas Algo?" should be used if you are speaking informally, like to a child, employee, or friend."Necesita Algo?" should be used if you are speaking to an employer, a parent, someone older than you, or a stranger.
Informally, it would be "tu hermanastra." In a formal context, or when speaking to a stranger or someone older than you, etc., it would be "su hermanastra."
You would say "She is older than her." "Her" is the correct pronoun to use in this comparison.
Heself is not a pronoun, actually it is not a word. Himself is a male reflexive pronoun Herself is a female reflexive pronoun
Thou is a pronoun, specifically a second person singular pronoun. It is an older form of "you" used in Early Modern English.
Thou is an older version of you, and you is a pronoun, therefore, Thou is a pronoun.
Vous avez..... ? (for a stranger or someone older than you) or Tu as..... ? (for a good friend)
"or older" (talking about a living being) = o yotehr yashen (או יותר ישן)"or older" (talking about an object or city) = o yotehr atik (או יותר עתיק)
Formal means that you are talking to someone older than you or someone you would show respect to. Examples are ¿Como se llamas? you are asking someone like a child or someone your age what their name is. ¿Como te llama? is asking the same thing but you would use it when talking to someone older than you, or who is in a higher position than you are.
