Unstressed Pronoun Position

In Polish, certain personal pronouns have two forms: short (clitic) and long (stressed). Clitics lack their own stress and must attach to a 'host' word.

1. Placement Rules:

• Never at the start: A sentence cannot begin with a clitic. Use the long form if you must start with the pronoun for emphasis. While the reflexive pronoun się cannot start a sentence, an actual reflexive object can use stressed siebie at the beginning. Lexical or impersonal się is not freely replaceable with siebie, as in boję się or myje się je.
• Avoid the end: In long sentences, clitics avoid the final position because the end of a sentence naturally carries stress. However, in very short sentences (e.g., 'Widzę go'), they can be final.
• The Second Position: Clitics gravitate toward the second slot in a clause, immediately following the first stressed element (like a subject, adverb, or a subordinating conjunction such as że, gdy, or bo). Unstressed coordinating i and a generally do not provide that host. Ale does: Poszedłem do niego, ale go nie zastałem (I went to his place, but did not find him there).

2. Clitic Forms and Clusters:
First, note that the short/long distinction only exists in the singular for 'ja' (mi/mnie), 'ty' (ci/tobie, cię/ciebie), 'on' (mu/jemu, go/jego), and 'ono' (mu/jemu in the dative, and go/jego in the genitive; note that its accusative form is 'je', which lacks a long form). The feminine singular ('ona') and all plural pronouns do not have distinct short and long forms for stress.

When multiple clitics appear together, their internal order is strict. While conditional particles (by) or past tense endings usually come first, pronoun clitics follow a rigid hierarchy: Dative clitics strictly precede Accusative clitics, and Dative clitics strictly precede the reflexive pronoun się. The neutral standard order is mi się. A reversed się mi occurs in colloquial usage, but is not the model for neutral edited Polish here. Additionally, się strictly precedes the Genitive clitic go (e.g., Boję się go, never *Boję go się).

Note on specific forms: The pronoun mnie serves as both the stressed and unstressed accusative form for 'ja'. Additionally, go is not only an accusative clitic but also the short genitive form, which is crucial when dealing with genitive under negation.

3. Prepositions:
For pronouns that have a short/long distinction (like mi/mnie or go/jego), the short form can never follow a preposition.

• First and Second Person: Use the long form (e.g., ze mną, dla ciebie). These never take an 'n-' prefix.
• Third Person: Use the special 'n-form' (e.g., do niego instead of do go).
• No Distinction: Pronouns like 'nas', 'was', 'ich', 'ją', and 'je' do not have distinct short/long pairs. While 'się' cannot follow a preposition (use siebie instead), the others are used as-is (or with an 'n-' prefix for third-person forms like 'nią' or 'nich').

Się Before Object Clitics: The neutral adjacent order also places się before an accusative clitic: Myje się je łatwo (They are easy to wash; literally, one washes them easily). Here się marks an impersonal construction and je is its object. In Boję się go, go is genitive because bać się requires genitive.
