A more thorough explanation:

Definition: Alienism refers to the state, condition, or character of being an alien.

Example 1: John's alienism made it difficult for him to adjust to the new culture and customs of the country he had migrated to.

Example 2: The government's policies on immigration were criticized for promoting alienism and discrimination against foreigners.

These examples illustrate how alienism can refer to the experience of being an outsider or foreigner in a new place. It can also refer to the attitudes and behaviors that discriminate against or exclude those who are perceived as different or unfamiliar.
