Word of the Day October 8, 2026 – חלקיקים

A Hebrew word from today’s reading: חלקיקים (ḥelqiqim).

It means particles—in today’s article, researchers are studying tiny polyethylene particles buried in agricultural soil.

But inside חלקיקים you can spot a much simpler Hebrew word:

חלק (ḥeleq)—part, portion.

These words are part of the family of ח־ל־ק, a very productive Hebrew root, closely related to the ideas of division and sharing.

You’ll find it in:

• חלק (ḥeleq)—part, portion
• לחלק (leḥaleq)—to divide, to distribute
• חלוקה (ḥaluqa)—division, distribution
• חלקי (ḥelqi)—partial
• חלקיק (ḥelqiq)—particle
• חלקיקים (ḥelqiqim)—particles

The formation of חלקיק is especially telling.

A חלק is a part.

A חלקיק is a tiny part—a particle.

The ending ־יק here gives the word a diminutive meaning: something smaller than a regular חלק.

That’s why חלקיק fits so well in scientific language: a particle is a minuscule unit of a larger whole.

In today’s article, the researchers are therefore studying חלקיקי פוליאתילן—polyethylene particles—to learn how microplastics behave in agricultural soils.

So, behind a scientific term like חלקיקים, there’s a simple Hebrew idea:

a whole → a חלק → a חלקיק that’s even smaller.

Sometimes, all it takes is “breaking down” a scientific Hebrew word to make it suddenly much clearer.
