+## Interjections and commands
+
+The word "a" functions like a emotional interjection. It is usually either added
+at the end of a sentence or functions as a sentence on its own.
+
+> sina suwi a! -- You are so cute!
+
+More specifically, laughter is indicated with the sentence "a a a!" (ha ha ha!).
+
+The word "mu" substitutes for any sound made by any animal.
+
+The word "o" is used to address people and issue commands.
+
+When used on its own at the beginning of a sentence, it turns the rest of the
+message into a command.
+
+> o kute e mi! -- Listen to me!
+
+When used after a noun phrase, it addresses a person.
+
+> sina o! -- Hey, you!
+
+Both uses can be combined.
+
+> jan pali o, kepeken e ilo awen! -- Worker, use protective equipment!
+
+## Questions
+
+There are two ways to ask questions in toki pona.
+
+If you want to ask a yes-or-no question, you phrase the sentence normally, but
+replace the word being questioned with a "[word] ala [word]" structure.
+
+> sina pona ala pona? -- Are you okay?
+
+There are no words for "yes" and "no", so to answer positively, you repeat the
+verb, and to answer negatively, you add "ala".
+
+> pona. -- Yes.
+
+> pona ala. -- No.
+
+(From what I understand, this structure is similar to what is used in Mandarin.)
+
+> ona li pali ala pali? -- Are they working?
+
+> jan lili li moku ala moku? -- Are the children eating?
+
+Alternatively, you can add "anu seme" ("or what?") instead.
+
+> sina pona anu seme? -- Are you okay?
+
+For freeform questions, you start with a regular sentence, but replace the word
+you're interested in with "seme".
+
+> sina pali e seme? -- What are you (doing/working on)?
+
+## Names (unofficial words)
+
+So far, these pages only relied on native toki pona words to refer to things and
+people. But this is clearly not enough when you need to call someone by their
+name. For proper names, toki pona uses so-called "unofficial words". These are
+usually names of people, cities, countries, etc., taken from their native
+languages and adapted to toki pona's pronunciation rules. Unlike all toki pona
+words, they're spelled with the first letter capitalized.
+
+Unofficial words are always treated as adjectives, which means that before them
+is always a noun or a noun phrase describing what is being referred to.
+
+> jan Mimi -- (the person) Mimi
+
+> ma Kanata -- (the country) Canada
+
+> ma tomo Napoli -- (the city) Naples
+
+Thanks to different people interpreting both the native names and toki pona's
+sounds in different ways, there may ultimately be several different unofficial
+names for the same city or country's name.
+
+Also, people speaking toki pona are free to pick their own personal toki pona
+names, either by adapting the name from their native language or coming up with
+something new.

+% page 8a - creating toki pona unofficial words
+% /dev/urandom
+% march 2020
+
+To learn how to adapt names into unofficial words, first you have to know how
+toki pona's phonology works. The language's words consist of a series of
+syllables assembled under a (C)V(N) system. This means that each syllable
+consists of an optional consonant, then a vowel, then a nasal (the "n" sound).
+
+In addition, the sequences "ji", "ti", "wo" and "wu" turn into "i", "si", "o"
+and "u".
+
+Here's a table of all possible syllables.
+
+| a | e | i | o | u | an| en| in| on| un|
+|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|
+| a | e | i | o | u | an| en| in| on| un|
+|ja |je |   |jo |ju |jan|jen|   |jon|jun|
+|ka |ke |ki |ko |ku |kan|ken|kin|kon|kun|
+|la |le |li |lo |lu |lan|len|lin|lon|lun|
+|ma |me |mi |mo |mu |man|men|min|mon|mun|
+|na |ne |ni |no |nu |nan|nen|nin|non|nun|
+|pa |pe |pi |po |pu |pan|pen|pin|pon|pun|
+|sa |se |si |so |su |san|sen|sin|son|sun|
+|ta |te |   |to |tu |tan|ten|   |ton|tun|
+|wa |we |wi |   |   |wan|wen|win|   |   |
+
+Another rule is that you can't follow a vowel sound by a vowel sound, and you
+can't follow a nasal "n" sound with a "m" or another "n".
+
+Consonant sounds that don't exist in toki pona are replaced with similar sounds.
+For example, Rome (Roma) turns into "ma tomo Loma" and Jakarta turns into "ma
+tomo Sakata".
+
+| consonant | sounds it can represent         |
+|:---------:|:--------------------------------|
+| j         | y                               |
+| k         | k, g, sometimes h, French r     |
+| l         | l, r                            |
+| m         | m                               |
+| n         | n, syllable-final m             |
+| p         | p, b, f, sometimes v            |
+| s         | s, z, j, ch, sh, zh, ts, x      |
+| t         | t, d                            |
+| w         | v, w, sometimes r               |
+
+To deal with several consonant or vowel sounds in a row, you can either remove
+one of them or add an extra one.
+
+For names of cities, it's best to use pronunciations that people _in_ that city
+would use. For example, the city of Toronto, Canada is transcribed in the
+official book as "ma tomo Towano", not "ma tomo Tolonto".
+
+There are other rules, and interpretations of them differ. The "o kama sona e
+toki pona!" course features [this
+list of rules](http://tokipona.net/tp/janpije/tpize.php), and the official book
+has its own.
