This is the 523rd most frequent Hebrew word.
ם
The Hebrew character "ם" is the final form of the letter "מ" (Mem), used at the end of words.
In this sentence, "ם" is used as part of the pronoun "הם" (hem), which means "they" in masculine plural.
הם תמיד שמחים לעזור לאחרים.
They are always happy to help others.
Here, "ם" appears as the suffix to the noun "קסם" (kesem), meaning "magic," and denotes the singular masculine form of the noun in certain contexts.
קסם של אהבה התפשט בכל מקום.
A magic of love spread everywhere.
In this case, "ם" serves as the suffix in "מהם" (mehem), which translates to "from them" and is formed by attaching "ם" to "מ" (from).
