and also (and/also)

Often "and also" is redundant: "and" joins equal items; "also" adds an additional remark. Choose one or rephrase for clarity and rhythm.

Below are quick rules, compact memory tricks, and many copy-and-paste wrong/right rewrites for work, school, and casual sentences.

Short answer

Usually drop one: use "and" to join equals, or "also" to add a separate comment. Keep both only for deliberate pause, layered emphasis, or voice.

Redundant: I went to the store and also bought milk → I went to the store and bought milk.
Use "also" when it modifies the whole clause: She also called the manager.
Keep both rarely for tone: He hesitated, and also glanced back. (stylistic)

Core explanation: conjunction vs adverb

"And" is a coordinating conjunction that joins words, phrases, or clauses of equal weight. "Also" is an adverb that adds information or emphasis to an action or idea. If you're joining equals, prefer "and"; if you're adding a separate note, use "also" or start a new sentence.

Join equals → and: I packed my bag and my lunch.
Add information → also: I packed my bag. I also packed my lunch.
If both appear, ask whether the second word repeats meaning or creates intentional tone.

Wrong: I read the article and also learned new terms.
Right: I read the article and learned new terms.
Alt: I read the article. Also, I learned new terms.

When keeping both is acceptable

Use both sparingly when you want a pause, layered action, or when "also" clearly modifies the entire clause rather than duplicating a join.

Narrative pause: He paused, and also looked over his shoulder.
Layered action: They took photos and also interviewed residents. ("also" emphasizes an extra activity.)
Contrast or conflict: She apologized, and also insisted she was right. (creates tension)

Stylistic: She hesitated, and also glanced at the clock.
Work (emphasis): The team ran tests and also (importantly) validated the results.

Spacing and hyphenation notes

Treat "and also" as two separate words with a single space. Do not hyphenate or combine them. Use commas according to clause rules, not because both words occur.

Correct spacing: and also
No hyphen: avoid and-also or andalso
Comma use: I emailed him, and also called. (Comma depends on clause independence and clarity.)

Wrong: I emailed him,and also called.
Right: I emailed him, and also called.

Memory trick: one quick test

Ask: "Am I joining equals or adding a separate note?" If joining, use "and." If adding, use "also" or start a new sentence with "Also."

Joining equals? → and
Adding a remark? → also (or "Also, ...")
Need emphasis? → move "also" to clause start or split the sentence.

Wrong: She collected samples and also analyzed them. →
Right: She collected and analyzed samples.
Rewrite:
Wrong: I updated the slide and also sent it. →
Right: I updated the slide and sent it. Or: I updated the slide. I also sent it.

Fix your sentence: quick checklist and rewrites

When you spot "and also," run this checklist and pick the cleaner option.

1) Identify whether the elements are equal (nouns, verbs) or whether one is an extra comment.
2) If equal → use "and." If extra → use "also" or start a new sentence.
3) For emphasis, restructure: use a semicolon, split sentences, or move "also" to the clause start.

Rewrite:
Original: I updated the spreadsheet and also fixed the formulas. → Fixes: I updated the spreadsheet and fixed the formulas. / I updated the spreadsheet. I also fixed the formulas.
Rewrite:
Original: She phoned and also left a message. → Fixes: She phoned and left a message. / She phoned. She also left a message.
Rewrite:
Original: We met the client and also negotiated terms. → Fix: We met the client and negotiated terms.
Rewrite (tone): Original: He apologized, and also insisted he was right. → Keep for voice, or clarify: He apologized but insisted he was right.

Similar mistakes to watch for

Writers often stack connectors or adverbs. The remedy is the same: choose one clear connector or rephrase for precision.

Bad: both and also → Good: both ... and ... OR also ...
Bad: and then also → Good: and then ... OR also ...
Duplicate adverbs: "really very" or "absolutely essential" → choose the stronger single word.

Wrong: He both and also managed the project.
Right: He both managed and oversaw the project. Or: He also managed the project.
Wrong: In addition also, the board approved the plan.
Right: In addition, the board approved the plan. Or: Also, the board approved the plan.

Grammar deep-dive: commas, clause placement, and emphasis

"Also" modifies verbs or clauses; "and" joins parallel items. Commas follow clause rules-use them for clarity or when linking independent clauses, not because both words appear.

Also mid-clause: He also sent the file. ("also" modifies sent)
And joining objects: He sent the file and the report. ("and" connects objects)
Also at clause start: Also, we found discrepancies. (used like a sentence adverb)

Usage: Also at clause start: Also, the study included a control group.
Usage: And joining nouns: She ordered coffee and cake.
