By in Italian has several translations. Use da for the person responsible for an action in a passive sentence, in for many forms of transport, entro for a deadline, and vicino a when you mean “near.” The right choice depends on the relationship expressed by “by,” rather than the English word alone.
Quick answer:
By = da, in, entro, or vicino a, depending on meaning. Examples: scritto da Maria — written by Maria; in treno — by train; entro venerdì — by Friday.
How Do You Say By in Italian?
There is no one Italian preposition that covers every use of English by. Consider “written by Anna,” “by bus,” “by Monday,” and “by the window.” They describe an agent, a means of transport, a deadline, and a nearby location. Italian commonly uses different expressions for these meanings.
Example: Questo libro è stato scritto da Anna. — This book was written by Anna.
Da is a useful first translation to learn, but it is not a universal substitute. It also has other meanings, including “from” and, in some contexts, “at someone’s place.” Learn the whole construction before deciding that da must mean “by” whenever you see it.
A practical method is to replace the English “by” in your mind with a more specific idea: “performed by,” “using transport,” “no later than,” or “near.” This clarifies the intended meaning and makes the Italian choice much easier.
Main Italian Translations of By
1. Da — By an Agent
Use da to introduce who performs an action in a passive sentence. La lettera è stata scritta da Luca means “The letter was written by Luca.” The focus is on the letter, while da Luca identifies the writer.
With an active sentence, no such preposition is needed: Luca ha scritto la lettera means “Luca wrote the letter.” Both sentences describe the same basic action, but their grammar and focus differ. The English passive construction is what makes “by” relevant here.
For a book’s authorship, Italian also often uses di: un libro di Calvino, “a book by Calvino.” Compare this noun phrase with un libro scritto da Calvino, “a book written by Calvino.” The word scritto changes the construction, so the preposition changes too.
2. In — By a Means of Transport
In treno means “by train,” in autobus means “by bus,” and in macchina means “by car.” Vado al lavoro in treno is “I go to work by train.” Do not use da merely because the English translation contains “by.”
Other common expressions include in aereo, “by plane,” and in bicicletta, “by bicycle.” For walking, say a piedi, “on foot.” Transport expressions are useful to memorize as complete phrases rather than deriving them from an English preposition.
3. Entro — By a Deadline
Entro expresses a limit within which something must happen: entro venerdì, “by Friday,” and entro le sei, “by six.” Devo finire entro venerdì means “I have to finish by Friday.” The action needs to be completed no later than the stated limit.
Do not confuse a deadline with an exact appointment time. Alle sei means “at six,” while entro le sei means “by six.” Fino alle sei means “until six” and can describe an activity continuing up to that time. These are three different time relationships.
4. Vicino A — By or Near a Place
If “by” means “near,” use an expression such as vicino a. Un tavolo vicino alla finestra means “a table by the window” or “a table near the window.” Accanto a means “next to” and can describe a more directly adjacent position.
For “by the sea,” vicino al mare communicates being near the sea. Other expressions, such as sul mare, may describe a waterfront location in an appropriate sentence. Choose according to the actual location instead of assuming every English “by” expresses the same distance.

How to Pronounce the Main Expressions
Da is a short syllable with a clear a, approximately “dah.” In has a short, clear i vowel. Avoid heavily stressing either preposition when the important information is the following person, vehicle, or place.
Entro is approximately EN-troh, with stress on the first syllable. Vicino is approximately vee-CHEE-noh: the c before i has a sound like English ch. The a following it belongs to the full expression vicino a.
Practice the expression with its following noun. Vicino alla finestra flows as a phrase, and the double l in alla is held longer than a single consonant. English sound guides are approximate, so listen to the whole phrase and copy the vowel rhythm.
Combining Da with Articles
When da comes before a definite article, the two combine. This matters in passive expressions such as preparato dal cuoco, “prepared by the cook.” Learn the combined forms alongside the noun’s article.
- da + il = dal — dal cuoco, by the cook
- da + lo = dallo — dallo studente, by the student
- da + la = dalla — dalla maestra, by the teacher
- da + l’ = dall’ — dall’autore, by the author
- da + i = dai — dai bambini, by the children
- da + gli = dagli — dagli studenti, by the students
- da + le = dalle — dalle ragazze, by the girls
These forms do not always mean “by” outside a passive sentence. Vengo dal lavoro means “I’m coming from work,” and Vado dal medico means “I’m going to the doctor.” The combined spelling tells you about da plus an article, while the sentence supplies the relationship.
Useful Fixed Expressions
Da solo or da sola means “by oneself” or “alone.” A male speaker can say Vado da solo, while a female speaker can say Vado da sola. The adjective changes to match the person described.
Per caso means “by chance.” Ci siamo incontrati per caso is “We met by chance.” A mano means “by hand,” as in fatto a mano, “made by hand.” Neither expression needs da simply because English uses “by.”
Uno per uno means “one by one.” Here the relationship is a sequence of individual items or people. These fixed expressions show why a short phrase is often the right unit to memorize: the Italian wording follows its own pattern.
Example Sentences
The examples below highlight an agent, transport, and a deadline. Identify the meaning first, then notice which Italian expression communicates it.
Use: Da introduces the person who performed the action in a passive sentence.
Use: In treno names the means of transport. A Firenze names the destination.
Use: Entro sets the deadline for completing the action. It does not mean that sending continues until tomorrow.
Common Mistakes
Do not use da for every English “by.” Learn in treno, entro domani, vicino alla finestra, and per caso separately. Also distinguish un libro di Anna from un libro scritto da Anna: authorship can appear in different grammatical constructions.
For time, keep “by,” “at,” and “until” separate. Entro le sei, alle sei, and fino alle sei express a deadline, a time, and an endpoint respectively. Finally, combine da with a following definite article rather than writing forms such as da il cuoco.
