<Li> Potential pause: A speaker is told to repeat a given sentence slowly, allowing for pauses . The speaker will tend to insert pauses at the word boundaries . However, this method is not foolproof: the speaker could easily break up polysyllabic words, or fail to separate two or more closely linked words (e.g. "to a" in "He went to a house"). </Li> <Li> Indivisibility: A speaker is told to say a sentence out loud, and then is told to say the sentence again with extra words added to it . Thus, I have lived in this village for ten years might become My family and I have lived in this little village for about ten or so years . These extra words will tend to be added in the word boundaries of the original sentence . However, some languages have infixes, which are put inside a word . Similarly, some have separable affixes; in the German sentence "Ich komme gut zu Hause an", the verb ankommen is separated . </Li> <Li> Phonetic boundaries: Some languages have particular rules of pronunciation that make it easy to spot where a word boundary should be . For example, in a language that regularly stresses the last syllable of a word, a word boundary is likely to fall after each stressed syllable . Another example can be seen in a language that has vowel harmony (like Turkish): the vowels within a given word share the same quality, so a word boundary is likely to occur whenever the vowel quality changes . Nevertheless, not all languages have such convenient phonetic rules, and even those that do present the occasional exceptions . </Li> <Li> Orthographic boundaries: See below . </Li>
