When I was around ten I and my best friend learnt
enough of the ape language in Tarzan comics to
have 'conversations' in it.  He wouldn't play
along when I wanted to make vocab additions,
not to mention learning my own nascent conlang.

Was this -ir- morpheme from Spanish _ir_ "to go"
used as a relex of English "going to"?

At one point I created a "Future Swedish" which
had developed inflectional person endings from
personal pronouns. The idea built on the fact
that Swedish has 'inverted word order' (actually
the old Germanic verb-second rule) when the
phrase starts with a temporal adverb, so from
phrases like

- _Då gick jag_ "Then went I"
- _Nu går jag_ "Now go I"
- _Sen går jag_ "Afterwards go I"

Future Swedish developed complex verb forms

- _doyikya_ 'I went'
- _nûgoya_ 'I go'
- _sengoya_ 'I'll go'

For a first conjugation verb like _tala_ 'speak',
where the past tense ending -de of _talade_
'spoke' is usually silent in colloquial Swedish
the former adverbs became the sole tense markers:

- _dotalaya_ 'I spoke'
- _nûtalaya_ 'I speak'
- _sentalaya_ 'I'll speak'

The personal endings were as follows:

Singular
1. _Nu talar jag_ > _nûtalaya_ (*)
2. _Nu talar du_ > _nûtalarû_ (**)
3. _Nu talar den_ > _nûtalare_ (***) Plural
4. _Nu talar vi_ > _nûtalawi_
5. _Nu talar ni_ > _nûtalani_
6. _Nu talar dom_ > _nûtalarow_ (****)

(*) Future Swedish was r-dropping, and in addition
remaining /rr/ had become /Z/ written _j_ distinct
from /4/ _r_ < /r/. Otherwise both vowel and
consonant lengt was lost, which caused former length-
dependent differences in vowel quality to become
phonemic, so that there were twelve vowel phonemes
each with its own letter: _a â ä e ê i o ô ö
u û ü_. These twelve letters did *not*
correspond to the twelve vowel phonemes of many
Gautic accents of Swedish; rather there had been
first a split between all long and short vowels
and vowels with following /r/ followed/accompanied
by some mergers:

- _a_ /A/ < /a:/, /a(:)r/
- _â_ /a/ < /a/
- _ä_ /&/ < /E(:)r/
- _e_ /e/ < /e:/, /e:r/, /i/
- _ê_ /E/ < /E(:)/
- _i_ /i/ < /i:/, /i(:)r/
- _o_ /o/ < /o(:)/
- _ô_ /9/ < /2/, /2(:)r/, /8/
- _ö_ /2/ < /2:/, /8(:)r/
- _u_ /u/ < /u(:)(r)/
- _û_ /8/ < /8:/, /y/
- _ü_ /y/ < /y:/, /y(:)r/

As can be seen the spelling of Future Swedish
was influenced by Future French and Future
German. The not very well developed idea was
that the orthographic traditions of the
languages of Northern Europe were lost.
Apheresis, syncope and consonant cluster
simplification made Future Swedish look similar
to Japanese or an African language:

- _Sen *arrangerar jag färdigt hans kärra_
- 'I'll finish fixing his car(t)'
- > _Sejâheya hwädi acäja_

As can be seen Future Swedish was also nasal and
/h/ dropping; FS /h/ was from Contemporary Swedish
/X/: _arrangera_ /arraN'Xe:ra/ became _-jâhe-_
'fix, mend'.

(**) Contemporary Central Swedish has a sandhi
rule whereby cliticized pronouns beginning in /d/
change this to /r/, but I later invented a general
rule whereby /rd/ [d`] > /4/.

(***) The /rd/ > /4/ rule, /h/ loss and nasal loss
conspired to make clitic _den_ 'that' _det_ /de:/
'that' (neuter) _hon_ 'she' and _han_ 'he' merge
into a single ending _-re_. IIRC poetical FS had
separate feminine _-ru_ and _-ra_ endings.

(****) Postvocalic /m/ was not totally lost, but
rather changed into /w/. Nasals before stops were
also preserved.

Browsing around in the old binders I even found
"The North Wind and the Sun" in Future Swedish.
It is clear that I failed to predict some changes
in pronunciation, vocabulary and grammar in recent
Swedish, like the breaking up of obstruent +
sonorant clusters with [@], the now ubiquitous
filler word _typ_ 'like' and the loss of _att_
as an infinitive marker.

Smooth contemporary Swedish translation:

En gång grälade Nordanvinden och Solen om vem av
dom som var den starkaste. Just då kom det en
kille/man gående på vägen klädd i en tjock
jacka/rock. De bestämde att den av dem som kunde
få av killen jackan var den starkaste.
Nordanvinden blåste värre och värre men då
frös killen bara värre och värre så han
knäppte han sin jacka och knöt sin halsduk
hårdare om sin hals. Så skulle Solen försöka.
Solen sken varmare och varmare och då tog killen
av sig sin jacka. Så gick det till när Solen
bevisade att han var den starkaste av dem.
