That Japanese word means something different on-site!

Hi! It’s Sensei.

You’ve worked hard to study Japanese, haven’t you? But when you go to the site (Genba / 現場), your seniors (Senpai) might be shouting “words you know, but with completely different meanings.”

“Nameru-na!” “Barase!” “Aore!”

To avoid panicking when you hear these, let’s preview the “True usage” of these words.

01. Hatsuru (はつる)
Hatsuru

General meaning: (A rare word not commonly used in daily life)

On-site meaning: Chipping or breaking concrete

“Hatsutte-oite!” means to crush concrete to adjust its shape.

02. Barasu (ばらす)
Barasu

General meaning: To reveal a secret

On-site meaning: To dismantle or clean up

“Ashiba-o-barasu” doesn’t mean telling a secret; it means dismantling the scaffolding.

03. Nameru (なめる) ★Be Careful
Nameru

General meaning: To lick with your tongue

On-site meaning: To strip the head of a screw

If someone says “Neji nameru-na!”, they aren’t talking about tasting it—they mean “Don’t break the screw!”

04. Yojou (養生)
Yojou

General meaning: To rest and recover health

On-site meaning: Curing or protecting from scratches/dirt

Laying blue sheets on the floor to protect it is called “Yojou” on-site.

05. Sumidashi (墨出し)
Sumidashi

General meaning: (Rarely used word)

On-site meaning: Marking reference lines on floors/walls

An important preparation where you mark correct positions with pens or string.

06. Momu (もむ)
Momu

General meaning: To massage shoulders or body

On-site meaning: Driving in a screw with a drill

If someone says “Bisu-o-momu”, don’t give a massage—use the drill!

07. Nigeru (逃げる)
Nigeru

General meaning: To run away

On-site meaning: Shifting position or creating clearance

“10mm migi-ni nigete!” means “Shift the position 10mm to the right,” not running away.

08. Aoru (あおる)
Aoru

General meaning: Tailgating or provoking (often used in driving)

On-site meaning: Moving something using leverage

It refers to the action of using strong force to move a heavy object.

09. Neru (練る)
Neru

General meaning: To knead bread or elaborate a plan

On-site meaning: Mixing cement and water

The action of making mortar or concrete. It’s a job that requires strength.

10. Matagu (またぐ) ★Never do this!
Matagu

General meaning: To step over something

On-site meaning: A dangerous action that is prohibited

Stepping over tools, materials, or especially “safety harnesses” is bad manners and dangerous because you might trip!

Summary: Enjoy the “Differences” in meaning!

“Nameru” isn’t about tasting, and “Barasu” isn’t about telling secrets.

If your senior is shouting on-site, don’t think “I’m being scolded!” It’s okay. They are just teaching you an “action with a different meaning.”
