Formal Tamil is mainly used in literature, official documents, and newspapers. It follows strict Tamil grammatical rules and sentence structures. This form is also known as Eluthu Tamil (எழுத்து தமிழ்), which means “written Tamil.” Let’s see some examples.

|---|---|---|
| Be careful | பாத்துக்கோங்க | pathukonga |

Key Differences Between Formal And Informal Tamil
Written Tamil is commonly used in literary settings, such as newspapers and official documents. However, for everyday conversations, informal Tamil is used. Here’s a quick look at the key differences between formal and informal Tamil:
1. The Usage Of Tamil Pronouns
In formal Tamil, polite pronouns are used to show respect, especially when referring to elders.
Example: He will come tomorrow- Avar naalai varuvaar (அவர் நாளை வருவார்) — Here, Avar is a respectful pronoun.
When it comes to informal Tamil, pronouns are more relaxed and casual.
Example: He will come tomorrow- Avan naalai varuvaan (அவன் நாளை வருவான்) — Avan is a casual pronoun, typically used when referring to friends or younger individuals.
| English | Formal Tamil | Informal Tamil |
|---|---|---|
| He/She | Avar(அவர்) | Avan/Aval (அவன்/அவள்) |
| You | Neengal(நீங்கள்) | Nee (நீ) |
| They | Avargal(அவர்கள்) | Avanga (அவங்க) |
2. Tamil Sentence Formation
In formal Tamil, sentences are fully formed and follow proper grammatical structure.
Example: How are you?-Neengal eppadi irukireergal ( நீங்கள் எப்படி இருக்கிறீர்கள்? )
In informal situations, Tamil sentences are often shortened, and grammar rules are more flexible.
Example: How are you?-Eppadi iruka? (எப்டி இருக்க?)
3. Tamil Verb Endings
In formal Tamil, verb endings like -kiren (கிறேன்), -kirar (கிறார்), and -aargal (ஆர்கள்) are used to show politeness and maintain grammatical accuracy.
Example: He is coming-Avar varu-kirar (அவர் வரு-கிறார்)
In informal Tamil, verb endings are more relaxed and casual. Common informal endings include -ren (றேன்), -ru (ரு), -raan (றான்), -aal (ஆல்), -da (டா), and -di (டி).
Example: He is coming-Avan varuki-raan-(அவன் வருகி-றான்.)
4. Tamil Fillers
Fillers are generally avoided in formal conversations. However, in informal Tamil, however, fillers like machi (மச்சி), da (டா), and di (டி) are commonly used to add a friendly or casual tone.
Hey dude, where are you going?-Machi, engada pora? (மச்சி, எங்கடா போற?)
5. How To Use the Word “No” In Tamil
In formal settings, the word no is expressed as illai (இல்லை) or vendam (வேண்டாம்).
Example: There is no milk in that shop –Anta kadayil paal illai (அந்தக் கடையில் பால் இல்லை).
In informal Tamil, more casual forms like la (ல) and venam (வேணாம்) are used for “no.”
Example: There is no milk in that shop-Anta kadayil paal illa (அந்தக் கடையில் பால் இல்ல).

6. How To Show Respect In Tamil
In formal conversation, we should avoid direct commands. Instead, we must use polite phrases, and also follow pronunciation rules strictly.
Example: Please come here-Thayavu seithu ingey varungal (தயவு செய்து இங்கே வாருங்கள்)
On the other hand, in informal Tamil, we can use direct commands with pronunciation changes. These variations can differ depending on the region.
Example: Come here-Inga va( இங்க வா)
