The meaning of 'Objekt' (object) depends strongly on the context. In everyday language, it is a physical object; in real estate, a house or apartment; in grammar, a part of a sentence; and in computer science, a programming element.

The agent offered us a beautiful property on the outskirts of town.
In everyday speech, 'Objekt' (object) is often used for unclear, strange, or technical-looking items. It often sounds more formal or detached than 'Ding' (thing) or 'Sache' (thing/matter).
Die Polizei untersucht ein unbekanntes Flugobjekt.
The police are investigating an unidentified flying object.
In the real estate context, 'Objekt' (property) is often used with certain verbs. Typical phrases are 'ein Objekt besichtigen' (to view a property), 'ein Objekt mieten' (to rent a property), or 'ein Objekt kaufen' (to buy a property).
Wir möchten das Objekt am Wochenende besichtigen.
We would like to view the property at the weekend.
When 'Objekt' (object) is mentioned in a linguistic context, it is almost always about grammar. Signal words here are 'Satz' (sentence), 'Verb' (verb), 'Akkusativ' (accusative), 'Dativ' (dative), or 'Genitiv' (genitive).
Kannst du das Objekt in diesem Satz bestimmen?
Can you identify the object in this sentence?
When a person or thing is the target of feelings, 'Objekt' (object) is often used in fixed expressions. Common ones are 'Objekt der Begierde' (object of desire), 'Objekt des Interesses' (object of interest), or 'Objekt der Forschung' (object of research).
Das neue Auto wurde schnell zum Objekt seiner Begierde.
The new car quickly became the object of his desire.
In computer science, you can recognize this meaning by typical words from programming. These include 'Klasse' (class), 'Methode' (method), 'Instanz' (instance), or 'Variable' (variable).
Jedes Objekt in dieser Programmiersprache hat spezifische Eigenschaften.
Every object in this programming language has specific properties.
thing / matter
'die Sache' and 'das Objekt' can both mean an object that you can see or touch. 'Sache' is the normal everyday word, especially when you do not want to or cannot say exactly what it is. 'Objekt' sounds more precise, factual, or technical. It is used, for example, in reports, in science, or when something is described neutrally. The words can be confused because both can point to a thing. In everyday language, 'Sache' usually sounds more natural; 'Objekt' fits better when you are speaking in a detached or technical way.

The police found an unknown object in the garden.
Auf dem Tisch liegt eine kleine Sache, aber ich weiß nicht, wem sie gehört.
There is a small thing on the table, but I don't know who it belongs to.
