Awkward Ordinals

Write code that takes a positive integer and outputs the awkward ordinal name from the test cases. Notice that these are not the conventional ordinal names.

Input

• A positive integer from the test cases.
• You are not required to support any input not listed in the test cases.

Output

• The corresponding string from the test cases.
• This must be in the exact format shown, including having spaces in and only in the specified places.

Test cases

Test cases are in the format input:output where the input is a positive integer, and the output is made up solely of lower case letters and sometimes spaces.

There are 248 test cases, spread between 1, 2, 3, 4, and 5 digit inputs.

Conversion

To convert a number to its awkward ordinal, split the number into a multiple of 20 and a remainder less than 20.

• If the multiple of 20 is zero, the remainder becomes a conventional ordinal.
• If the remainder is zero, the multiple of 20 becomes an awkward ordinal, which is the awkward cardinal ten times less stripped of spaces and followed by "tieth".
• Otherwise, the multiple of 20 becomes an awkward cardinal followed by a space then the remainder as a conventional ordinal.

To convert a number to its awkward cardinal, split the number into a multiple of 20 and a remainder less than 20.

• If the multiple of 20 is zero, the remainder becomes a conventional cardinal.
• If the remainder is zero, the multiple of 20 becomes an awkward cardinal, which is the awkward cardinal 10 times less stripped of spaces and followed by "ty".
• Otherwise, the multiple of 20 becomes an awkward cardinal followed by a space then the remainder as a conventional cardinal.

Example code

Assuming you already had functions for the conventional ordinals and cardinals less than 20, and a spaceless function that returns its input with all spaces removed, the following Python code would give the results as described above (note that this is for ease of explanation - you cannot assume existence of non-existent functions in your answer):

def awkward_ordinal(n):
  if n<20:
    return conventional_ordinal(n)
  if n%20==0:
    return spaceless(awkward_cardinal(n/10))+"tieth"
  return awkward_cardinal(n-n%20)+" "+conventional_ordinal(n%20)

def awkward_cardinal(n):
  if n<20:
    return conventional_cardinal(n)
  if n%20==0:
    return spaceless(awkward_cardinal(n/10))+"ty"
  return awkward_cardinal(n-n%20)+" "+conventional_cardinal(n%20)

So 40 becomes the ordinal fortieth but 46 becomes the cardinal forty plus the ordinal sixth to give forty sixth.

Notice that the algorithm as described would give fourtieth rather than fortieth and fourty sixth rather than forty sixth. Passing the test cases will require being aware of such exceptions to the general rule. These are described below.

Cardinals and ordinals 1 to 19

The numbers up to 19 become cardinals and ordinals in the conventional way, giving cardinals one to nineteen and ordinals first to nineteenth (with the conventional exceptions of first, second, third, fifth, eighth, ninth, twelfth, fifteenth, and eighteenth instead of oneth, twoth, threeth, fiveth, eightth, nineth, twelveth, fiveteenth, and eightteenth).

Larger cardinals

A number that is a multiple of 20 becomes a cardinal by dividing it by 10 and then adding "ty" to the cardinal form of that result, omitting any spaces, with the following exceptions:

Larger ordinals

A number that is a multiple of 20 becomes an ordinal by dividing it by 10 and then adding "tieth" to the cardinal form of that result, omitting any spaces, with the following exceptions:

Conversion examples

No exceptions

• 66 = 60 + 6 = 6*10 + 6
• Ordinal is (6)ty (6)th giving sixty sixth.

Exceptions

• 48 = 40 + 8 = 4*10 + 8
• Ordinal would be (4)ty (8)th giving fourty eightth but exceptions make it forty eighth instead.

Remainder mod 20 larger than 10

• 74 = 60 + 14 = 6*10 + 14
• Ordinal is (6)ty (14)th giving sixty fourteenth.

No remainder mod 20

• 60 = 60 + 0 = 6*10 + 0
• Ordinal is (6)tieth giving sixtieth.

Splitting twice

• 474 = 460 + 14 = 46*10 + 14
• Ordinal is (46)ty (14)th but first 46 needs to be split (because it is more than 19).
  • 46 = 40 + 6 = 4*10 + 6
  • Cardinal would be (4)ty 6 giving fourty six but exceptions make it forty six instead. Spaces will be omitted before combining with ty.
• Ordinal is (fortysix)ty (14)th giving fortysixty fourteenth.

Splitting four times

• 37381 = 37380 + 1 = 3738*10 + 1
• Ordinal is (3738)ty (1)th but first 3738 needs to be split.
  • 3738 = 3720 + 18 = 372*10 + 18
  • Cardinal is (372)ty 18 but first 372 needs to be split.
    • 372 = 360 + 12 = 36*10 + 12
    • Cardinal is (36)ty 12 but first 36 needs to be split.
      • 36 = 20 + 16 = 2*10 + 16
      • Cardinal is (2)ty 16 giving twoty sixteen but exceptions make it twenty sixteen.
    • Cardinal is (twentysixteen)ty 12 giving twentysixteenty twelve.
  • Cardinal is (twentysixteentytwelve)ty 18 giving twentysixteentytwelvety eighteen but exceptions make it twentysixteentytwelfty eighteen.
• Ordinal is (twentysixteentytwelftyeighteen)ty (1)th giving twentysixteentytwelftyeighteenty oneth but exceptions make it twentysixteentytwelftyeighteenty first.

Scoring

This is a code golf challenge. Your score is the number of bytes in your code.

Explanations are optional, but I'm more likely to upvote answers that have one.
